CHAPTER 1 SETTING UP SC-lo/l5 In this chapter, we’ll show you how to unpack your new SG-lo/15 printer, set it up in the right location, and get it ready for you to load it with paper and start printing. But first . . . WHERE SHALL WE PUT IT? Before you do anything else, give some thought to where you’ll be using your printer.
Figure l-l. Inside the carton you should have received: 1) SG-lo/15 printer, 2) paper separator, 3) paper guide, 4) platen knob, 5) spare fuse, 6) ink ribbon, and 7) this user’s manual.

RELEASE LEVER - On top, near the left rear corner. You’ll be using this particular control often. What it does is control the pressure of the paper against the platen. Its position is crucial to feeding the different paper types - sprocket and single sheets.
Release lever Figure 24. The paper release lever has two settings: “F” for friction feed and “T” for tractor feed. H Loading single sheets Paper width must always be between 8 and 10 inches (8 and 15 inches for the SG-15), and paper thickness between .
6. Press the ON LINE button until the ON LINE light goes off. 7. Press the L.F. button to roll the paper in until it appears on the front side of the platen, about where you want the first line to start printing. NOTE: To straighten paper (if it’s in crooked): l Move the release lever to “T” position.
To use this kind of paper, you’ll need to install the tractor unit, with its two “sprocket” wheels to carry the paper along. To install the tractor, identify the two “snap levers” shown in Figure 2-6.
Tractor cover Figure 2-7. Open the tractor covers to expose the sprocket teeth. 4. Place the stack of fan-fold paper behind the printer. 5. Open the tractor covers, atop the right and left sprocket units, as shown in Figure 2-7. 6. Flip the clamp levers forward.
L Figure 2-8. SG-lo/15 ready to run with sprocket-feed paper. W Bottom feeding SG-15 The SG- 15 can be loaded with sprocket paper in two different ways-either from the back, as with SG-10,or through a slot in the bottom. To load SG- 15 from the back, follow the steps shown in the previous section.
5. Open the tractor covers, right and left (Figure 2-7). 6. Flip the clamp levers forward. This allows the two sprocket units to move freely right and left, so you can align them with the holes in the paper. 7. Pick up the first “sheet” and lift it up and through the slot in the bottom of the SG-15.
ADJUSTING THE GAP The gap is the space between the print head and the platen. Adjusting the gap is simply adjusting the printer to accommodate different thicknesses of paper. To make this adjustment, move the adjustment lever which is under the printer cover, immediately in front of the release lever shown in Figure 2-10.
(STAR mode; DIP switch 2-2 on) “warm-up” that permits you to check your installation of ribbon and paper, and the adjustment of the print head gap. Best of all, you don’t have to wait another minute - you can print the self-test without hooking up the SC&IO/15 to your computer! It’s as simple as 1, 2, 3.

Figure 3-1. SG-lo/15 has parallel interface as standard. CHAPTER 3 GETTING STARTED WITH SG-lo/15 You have assembled and tested your printer, and seen a quick sample of SG-10/15’s capabilities in the self-test. Now it’s time to do what you bought SG-IO/15 to do: print information from your computer.
USING COMMERCIAL SOFTWARE Many of you purchased SG-lo/15 to use with commercial software. You made a good choice because SG- lo/15 is com- patible with most commercial programs, from word processing programs to spreadsheet programs to accounting programs.
ask-key ). There are ASCII codes for all the letters of the alphabet, both lower case and capital, the numbers from 0 to 9, most punctuation marks, and some (but not all) of SG-10/15’s func- tions. ASCII codes are referred to in several different ways, depending on the way they are used.
<LF> - the abbreviation of its name ASCII 10 - its decimal value ASCII OAH - its hexadecimal value (the H signifies hex) CHR$( 10) - the way it’s used in BASIC control-J - the way you send it from a keyboard. There’s a chart in Appendix F that shows these side-by-side so that you can convert back and forth.
that we want to use condensed print. The code to switch SG-lo/15 into condensed print is ASCII 15, or control-O. So to switch on condensed type, use the /Output command and, after selecting D(isplay) and entering the range to print, select the S(etup) option, and the S(etup)-“Manual setup codes” sub option.
Entering the 4 is no problem; it’s a printing character so Easy- Writer won’t object (although in this case it’s not going to print). The Escape, however, is a non-printing character so it requires special handling. To enter the Escape code first enter control-O (hold the Ctrl key while you press the letter 0).
CHAPTER 4 CONTROLLING SG- 1 O/ 15 WITH BASIC Throughout the rest of this book we will be teaching you how to use SG-lo/15 ‘s features using the BASIC programming lan- guage in our examples.
ways, and hope that between this and your computer’s BASIC manual you will be able to stay with us. First on our list is Microsoft BASIC’s way of communicating with the printer. They just add an “L” to the beginning of the LIST and PRINT commands, making them LLIST and LPRINT.
LLIST it (or however your computer does it). We’ve crossed the first major hurdle-learning how to list programs on SC-10/l% Now we are ready to jump into the world of programming with SG-10/15. But first, there are a few fundamentals that we need to cover.
n Control codes SG-lo/15 uses many of the non-printing ASCII codes for control codes. These codes perform a function rather than printing a character. Let’s try an easy one right now: . . NEW 10 LPRINT CHR$(7) RUN Where did that noise come from? That’s SG-10/15’s bell.
1 1 Some of you fast students may have noticed that CHR$(69) is the same as “E”. That’s right, the program will work just as 1 1 f well if line 10 is changed like this: 10 LPRINT CHR$(27) "E"; That’s just another form of the same ASCII code, and it’s all the same to SG-10/15.
This is the command to turn on expanded print < ESC > , as we mentioned earlier, is the way we will indicate the escape code, which is ASCII code 27. A letter or number enclosed in quote marks (such as the “W” above) means that character should be sent to the printer (without the quote marks).
That’s it for the basics. You are ready to learn how to use the many features of SG-10/15. in STAR mode. There are some cases where you would use IBM mode with your computer, if you wish.

CHAPTER 5 PRINTING TEXT WITH SG-lo/15 Beginning with this chapter we will be exploring all the features of SG-10/15. In this chapter we’ll cover: l Near letter quality characters l Italics l Underli.

ued.Therefore, BASIC didn’t send a carriage return and line feed at the end of those lines. We just did this to illustrate that all these control codes can be used in the middle of a line. It’s easy to underline or italicize only part of a line. n Superscripts and subscripts SG-lo/15 can print in two different heights of characters.
“S” CHR$( l), and finally off in line 90. Again, everything prints on one line because of the semicolons. CHANGING THE PRINT PITCH In “printer talk,” character width is called pitch. Normally, SG-lo/15 prints 10 characters per inch. This is called pica pitch because it’s the same spacing as a standard pica typewriter.
.--_ 30 LPRINT "This line is CONDENSED pitch." 48 LPRINT CHR$(27) "B" CHR$(2) ; 'Select elite pitch. 50 LPRINT "This line is ELITE pitch." 60 LPRINT CHR$(27) "p" CHR$(l) ; 'Select proportional. 717~ LPRINT "This line is PROPORTIONAL spacing.
Expanded print set with CHR$(14) is automatically canceled at the end of the line. This is convenient in many applications, such as for one line titles. Note that you don’t need to put an < ESC > in front of the CHR$( 14), although < ESC > CHR$( 14) works just the same.
By combining expanded print with the four pitches, SG-lo/15 has eight different character widths available. Enter this program to see how the print pitches and expanded print can be combined: 18 'Demo pitches in combination with expanded mode. 241 LPRINT CHR$(27) "W" CHR$(l) ; 'Permanent expanded mode on.

Let’s try them and see what the difference is. The following table shows the control codes for getting into and out of double-strike and emphasized modes.
80 turns emphasized off, so that SG-lo/15 is set for normal printing. Look closely at the different lines of printing. In the line of double-strike printing each character has been printed twice, and they are moved down just slightly the second time they are printed.

will add the line feed for you. When you have DIP switch 2-3 off the printer will do the same thing when it receives a carriage return as it does when it receives a line feed. If you find that your printer double spaces when it should single space, then you probably need to turn DIP switch 2-3 on.
This is what you will get: This line +aciniJ is set to 10 This line spacing ic, s.et to 11 This line spacing is set to 12 This 1 ine spacing is set to 14 This 1inEt spacing is set to 15 Thic line spacing is E-et tc1 lb This line spacing is set to 17 This line spacing is set to 18 This 1 ine spat i ng i .
You may wonder why they picked l/72 of an inch as the in- crement for the line spacing command. There’s a good reason: the dots that the printer makes are l/72 inch apart.
The program works just the same as before, but the line spacing are just half (STAR mode) or one-third (IBM mode) what they were. This is because < ESC > “3” CHR$(n) sets the line spacing to n/144 inch in the STAR mode, or n/216 inch in the IBM mode.
without moving the printhead back to the left margin. The fol- lowing commands do just that. The < ESC > “J” CHR$(n) command causes the printer to make one line feed of n/144 inch (STAR mode), or n/216 inch (IBM mode), but does not change the setting of the line spacing.

The form feed (CHR$(J2)) in line 50 caused the printer to move to the top of a new page before printing the last two lines. A note to TRS-80 users: CHR$(12) is a problem code for the TRS-80. To send a form feed command to SG-lo/15 you must add 128 to it making it CHR$(140).
TOP AND BOTTOM MARGINS Many programs that use a printer don’t keep track of where they are printing on the page. This causes a problem when you get to the bottom of a page because these programs just keep on printing, right over the perforation. This makes it very hard to read, especially if a line happens to fall right on the perforation.
When you run this program it will print 150 lines right down the page and across the perforations. When it’s done line 60 sends a form feed to advance the paper to the top of the next page. Look at the lines that have printed near the perforations. Separate the sheets and see if any of the lines have been torn in half.
Always send a form feed after setting the top margin, or it will not work on the first page printed. That’s because the top margin only takes effect after a form feed. Line 14 sets the top margin, line 12 sets the bottom margin, and line 55 clears both margins when we are done.

CHAPTER 7 I FORMATTING YOUR OUTPUT You have probably used the tab and margin features on a typewriter. They make it easier to format the text on a page.
CHR$(9) is a problem with some computers. Some BASICS convert CHR$(9) to a group of spaces that act like a sort of pseudo-tab. This is fine if the computer and the printer have the same tab settings, but it doesn’t allow us to use our own tab settings on SG-10/15.
Table 7-1 Horizontal tab commands 1 Function 1 Mode 1 Control code I Advance to next tab position STAR 1 CHR$(9) IBM I CHRS(9) Set tabs at nl, n2, etc. 111 One-time tab of n spaces STAR <ESC > “b” CHR!$(n) IBM <ESC> “b” CHRS(n) Note: If your computer does not support lowercase characters, use CHR$(98) for “b.
110 RETURN The first thing that this program does is to branch to the subroutine that starts in line 70. This subroutine prints 80 X’s in a row. The first time that the subroutine is used, all the X’s fit in one line. Then line 30 sets the left margin to 10, and line 40 sets the right margin to 70.
Now, let’s set some vertical tabs of our own. Add these lines to the program: 12 LPRINT CHR$(27) "P" CHR$(lfl) ; 14 LPRINT CHR$(2@) CHR$(4@) CHR$(@) CHR$('d) ; < ESC > “P” is the command to set vertical tabs for the STAR mode.
I This doesn’t confuse SG- lo/ 15-it advances the paper to the next tab position which happens to be the first tab position on the next page. That’s nice, isn’t it? n A one-shot vertical tab command There’s a one-time vertical tab command that works just like the one-time horizontal tab command.
CHAPTER 8 SPECIAL FEATURES OF THE SG-lo/15 In the previous chapters we have learned about several groups of control codes. In this chapter we will look at more control codes. These codes don’t lit neatly into any of the groupings that we have studied, but they add a lot of capability to SG-10/15.
to remind an operator to change the paper or to make another adjustment to the printer. Note to Apple users: Entering a CHR$(7) will sound Apple’s bell; the code will not be sent to SG-10/15. You can try this by typing: LPRINT CHR$(7); - There are two other codes that affect the bell.
for the code to go on-line again. CHR$(19) is the code to turn SG- 10/l 5 off-line; CHR$( 17) returns SG- lo/ 15 to on-line status. n Printing to the bottom of the sheet Sometimes when you are using individual sheets of paper you may want to print near the bottom of a sheet.
- 1 Backspace, delete, and cancel text Backspace (CHR$(8)) “backs up” the printhead so that you can print two characters right on top of each other. Each time SG- 10/l 5 receives a backspace it moves the printhead one character to the left, instead of to the right.
H Unidirectional printing Unidirectional printing is a big word that means printing in one direction only. SG- lo/ 15 normally prints when the printhead is moving in both directions. But once in a while you may have an application where you are more concerned about how the vertical lines align than with how fast it prints.
again. Finally line 110 sends a form feed to advance the paper to the top of a new page, and then uses the master reset to restore SG-lo/15 to the power-on condition. You can also set SG-IO/l5 to print in one direction for one line only by using the command < ESC > “ < “.
H Block graphics characters and special symbols Besides the upper and lower case letters and symbols that we are by now familiar with, SC-lo/15 has a whole different set of characters that are for special uses.

In this chapter we have learned many different commands that have many different uses. In the next chapter we will make up for this diversity-the whole chapter only covers three commands! But they are some of the most powerful that SG-lo/15 offers. They give you the ability to create your own characters.
-.
CHAPTER 9 CREATING YOUR OWN CHARACTERS In this chapter we’ll cover: l Designing and printing your own characters l Designing proportional characters In the previous four chapters of this manual you’ve learned how to control the SG-lo/15 printer to give you dozens of dif- ferent typefaces.
Figure 9-1. The letter “C” is created by printing 15 dots. descenders (such as the lower case “p” shown) use the bottom seven pins. As the printhead moves across the page (in either direction-that’s what is meant by bi-directional printing) it prints one column of dots at a time.
But there is another area of memory in the SG-lo/15 reserved for user-defined characters. These are characters that you design and download into SG-10/15. When download characters are defined they are stored in RAM (random access memory), which allows you to define or modify them at any time.
Figure 9-5. Later in this chapter we’ll use this character to create a small graph.) You’ll notice that Figure 9-4 includes a lot of information around the grid. Don’t be intimidated; we’ll explain each item as we come to it in our discussion of defining and actually printing download characters.
character uses the top eight dots, write in a one next to the word “Descender” on the layout grid; if it uses the bottom eight dots, write in a zero. In our example, we’ll want the bottom of the flask to line up with the baseline of the other characters, so it will not be a descender.
64 32 16 btal m, m, m, m. m, m6 m, m, m, m,, m,, ASCII Code WRONG! Descender Start column End column M, = Descender l 128 + (Start l 16) + End -- Figure 9-6. Dots cannot overlap; those in immediately adjacent “half columns” will be ignored when the character is printed.
value. Some examples will make this clearer. As shown in Figure 9-7, if we add the numbers for the dots that print in a column, the sum will be a number in the range of 0 to 255. Each number from O-255 represents a unique combination of dots. So add up the values of the dots in each column using this system.
can define any positions except the defined control code positions. This means that once a character is defined and assigned a value (and the download character set is selected), you can use that character on the printer the same way you would any standard character.
Our chart would hardly be complete with just a picture of a chemist’s flask, so in Figure 9-9 we’ve made completed grids for some other symbols: an automobile and a gun (quite a strange mix of characters!). The information on the grids is now complete (except for proportional width data-a more advanced topic we’ll take up shortly).
We’ll be discussing proportional character widths in detail later in this chapter; for now, we’ll leave it at 11. The descender data was discussed earlier: to use the top eight pins, this bit should be 1; to use the bottom eight pins this bit should be 0.

Voila! It should have printed out the three characters we de- fined. Your printout should look like this: (If it doesn’t, check the last program we ran for errors, then rerun it.) Let’s find out if there are any other characters in the download RAM.

ERASING DOWNLOAD CHARACTER DEFINITIONS After you have defined a set of characters (a whole new al- phabet, perhaps) you may want to go back to using mostly standard characters with a few new user-defined characters mixed in.

As you know, the first bit of m0 is used to specify whether the character is a descender or ‘not. The next three bits are used to specify the starting print column (acceptable values are 0 to 7).

One thing to remember about defining proportional characters: a character cannot be wider than the specified width. That seems obvious enough! For example, if you specify a width of 6 for a character (starting in column 1 and ending in column 6), the seventh through eleventh columns of dots (if you specified any) will not print.
In the program that follows, we’ve used this technique to create some large numbers. Each digit is actually made up of four characters-two horizontally by two vertically. This means, of course, that you must define and print four characters for each finished digit.

(if you’re not sure which type of interface your computer has, check the appendix for your computer). So when do you use graphics and when do you use download characters? Practically anything you can do with graphics you can do with download characters, and vice versa.
it’s possible to have a graphics image as wide as 480 dots on SG-10 or 816 dots on SG-15. So to figure out how many columns of graphics data to expect, SG- lo/15 multiplies n2 by 256 and adds the value of nl.

n Combining text and graphics It’s also possible to mix text and graphics in one line. This can be useful for labeling charts or graphs, or even inserting fancy graphics in text.
paper. And it may be helpful to write the dot values (128, 64, 32, etc.) down the left side of each row. Then after you’ve filled in the “dots” that you want to print, it’s time to get out the old calculator again! Just as you did with download characters, add up the values of each column of dots; this makes up one byte.

and SG-IO/15 plotting the output, you can come up with some terrific business graphs, charts, and mathematical function plots. The best way to do this is to set up an array in memory. This is your “graph paper.” The first thing to do is to determine how big you want your output to be; this will determine the size of your array.

you need to change are the values in line 40. The array MASK% contains the values of the dots. (In order to make this program run on the most computers, we’re using only six pins for graphics. With many computers, you can use all eight available pins.
at a time. The variable A$ is used to build a string of all the columns of BIT% in a given row. As you can see, by taking the program in small pieces and analyzing it, graphics programming does not have to be difficult. If you want to try some other plots, try these (replace lines after 600 with the lines below).
HIGH RESOLUTION GRAPHICS Up until now all of the dot graphics printing we have done has been with SG-10/15’s normal density mode. This can give you some pretty sharp images at great speed. Sometimes though, you may want to create an image with even higher resolution.

So if quadruple density looks so great, why not use it all the time? Let’s try an experiment on your printer which will show just how the different density modes work. Using the “logo” program in this chapter, change line 60 to try each of the different modes.
Star’s engineers have given programmers a unique shortcut for program development though-double density double speed graphics. Although this mode requires just as much memory and computing time as double density, it prints at the same speed as normal density graphics.
