To thread the ribbon, slide the print head carriage ._ i manually to the right OP left, and the ribbon will slip down by itself into its proper position.
7 The mute cover reduces the printer’s operating sounds. Note the position of the guide pins on the mute cover as shown in Figure l-7. Holding the mute cover at each end, insert the guide pins into the cutout hooks on the printer cover. Hold the mute cover down onto the printer.
8 n Installing the font cartridge This printer is mounted the Prestige characters as standard. You can add one or two different character styles by installing the optional font cartridges to the printer. To install or change a font cartridge, start by turing off the power switch.

TYPE STYLE KEY - Changes the type style among four or six styles when the On Line indicator is off. QUALITY INDICATORS - Either DRAFT or LETTER glows green to indicate the character quality (set by the Quality key). QUALITY KEY - Changes the print quality every time it is pressed when the On Line indicator is off.
13 w Extra functions There are twelve more functions that are not directly specified on the control panel. You can access six of them by pressing one particular key when you turn on the power; six others are activated by pressing two control keys at once.
14 n Other controls There are other controls, not connected to the control panel. Some of the more important ones are: POWER SWITCH - The switch that turns the printer on and off is at the back, on the left side. PLATEN KNOB - This knob is at the middle of the right side and lets you turn the platen by hand, like a typewriter.
15 The paper bail holds the paper against the platen according to the setting of the release lever. The bail is opened when the release lever is in the top position, closed when the lever is in the second or third positions, and opened by the printer when the lever is in the bottom position.

I 26 but instead ask some questions about what your printer can do. The answers to the “most asked” questions are: Yes - this printer can do a “backspace”, and this printer can do a “hard- ware form feed”. With these questions answered, you are ready to start print- ing.
27 help of your program manual and the supporting chapters in this manual, you should be able to figure out how yours works. GENERAL CONCEPTS Each word processing program has a way to get out of the standard text entry mode in order to accept the special printer function codes.
28 reset code and resets the printer to its DIP switch settings. These print characteristics are the same as the ones used by the printer when it is first turned on. The code sequence for master reset is (ESC) “@“. By check- ing the ASCII equivalents in Appendix D, you can see that the decimal expression is 27 64.
Second, read Chapter 4 which describes them in greater detail and shows examples of how they are used in BASIC programm- ing. The functions will, for the most part, act the same in your word processing program. Understanding what’s available and how they perform will help you use them correctly in your documents.

34 Now, change the pitch setting in the next line to pica by set- ting a new ruler line: Ruler Name - pica; Character Pitch - 10. Use the print control key S (for italic) to highlight the second sentence in the paragraph. Move the cursor to the “E” in “Enclosed” and (in the sentence mode) use the ALT and S keys to highlight the sentence.

Remember, all the codes can be found in Appendix D of this manual. Also, keep in mind that print control keys can be combined in your document such as boldface and underline.
36 It is also possible to define the - PA (alternate pitch) com- mand to change the print pitch of your document. The Word- Star User’s Manual fully describes the use of these * P func- tions. You should refer to your manual if you need help with them.
37 You can specify the range to print in all the normal ways: by pointing, by typing the cell addresses of the endpoints, by enter- ing a range name, or by using the F3 key to point to a range name.

CHAPTER 4 PRINTING WITH BASIC Subjects covered in Chapter 4 include- . Listing BASIC programs on the printer l How a program prints things l Control codes, escape codes, and command syn- tax l Selecti.
44 SOME BASICS OF BASIC 4 First steps The first things that a beginner learns to do are to list a pro- gram and to print a character string. Certainly these are the easiest operations one can do, but even they may depend on what computer you have. In Microsoft BASIC, we can list all the steps in a program by entering LIST.
45 w ASCII codes and the CHR$ function You can talk to your computer in BASIC, but your computer and your printer talk to each other in what are known as ASCII codes. In the ASCII code, each number from 0 to 255 has a par- ticular meaning - 36, for example, makes the printer print a dollar sign.
4fi - the “control” key and one other. The other key determines what code is sent - pressing the control (CTRL) key and A sends ASCII code 1, CTRL B sends ASCII code 2, and so on. Your printer has a lot of control codes to let you do some useful things.
47 B The escape codes Back when the ASCII system was set up, computer equip- ment was relatively simple and thirty-three control codes were considered sufficient at the time.
So for our example above, any of these BASIC statements will have the same result: LPRINT CHR$(27);CHR$(87);CHR$(l) LPRINT CHR$(27);CHR$(87);CHR$(49) LPRINT CHR$(27);"W";CHR$(l) LPRINT CHR$(.
49 n Draft and Letter Quality characters This printer’s Letter Quality (sometimes abbreviated as LQ) character set is ideal for correspondence and other important printing, as it produces very high quality characters. In addi- tion, your printer prints draft quality characters.
50 Table 4-1 Letter quality commands Function Letter quality ON Letter quality OFF Control code (ESC) “x” 1 (ESC) “I” 2 (IBM-P mode only) (ESC) “x” 0 (ESC) “I” 0 (IBM-P mode only) n Italic printing Italic letters are letters that are slanted to the right.
Chapter 3, and set the Italic type, then run the program again. You should get like this: This line is in ITALIC characters. This line is in ROMAN characters. As you can see, this time the printer ignored the control codes to set or cancel italic characters.
52 characters before line 70 switches printer back to internal LQ characters with an (ESC) “k” CHR$(O) command. You can control the font styles with the extra functions with the control panel.
53 In this program underline is turned on in line 30 with (ESC) “ - ” 1, and then off in line 50 with (ESC) “ -” 0. The overline is turned on in line 70 with (ESC) “-” 1, and then off in line 90 with (ESC) “-” 0. There’s a new aspect to this program, though.
54 Here line 30 turns on superscripts with (ESC) “S” 0. It’s turned off in line 50 with (ESC) “T”. Then between printing text, subscripts are turned on in line 70 with (ESC) “S” 1, and finally off in line 90. Again, everything prints on one line because of the semicolons.
55 When you run this program you should get this: This line is SEKI-CONDENSED pitch, This line is ELITE pitch. This line is PICA pitch (normal). Line 20 turns on semi-condensed pitch with (ESC) “g”. Line 30 prints the line at 15 characters per inch.
return with CHR$(20), as done in line 50. Sometimes you may wish to stay in expanded print for more than one line. Change your program to this: 10 ’ Demo of permanent expanded mode 20 LPRINT CHR$(27.
Demonstration of CONDENSED printing. 57 Condensed print set with CHR$(15) stays on until you turn it off with CHR$(18). Note that you don’t need to put an (ESC) in front of the CHR$(15), although (ESC) CHR$(lS) works just the same.
220 LPRINT "This is EXPANDED SEMI-CONDENSED." 230 LPRINT CHR$(27);"M"; 240 LPRINT "This is EXPANDED ELITE." 250 LPRINT CHR$(27);"P"; 260 LPRINT "This is EXPANDED PICA." 270 LPRINT CHR$(27);"WO" 280 END Here’s what you should get from this program: This line is CON3ENSED ELITE pitch.

60 this: boldface and emphasized print. Both of these go over the characters twice, but they use slightly different methods to darken the characters. Let’s try them and see what the dif- ference is. The following table shows the control codes for getting into and out of boldface and emphasized modes.
your printer is set for normal printing. Look closely at the different lines of printing. In the line of boldface printing each character has been printed twice, and the paper was moved up slightly the second time they were printed. In emphasized printing, the characters are moved slightly to the right the second time the printer prints.
For example, if you want to select elite expanded boldface print, you would calculate the value of n like this: Elite 1 Boldface 16 Expanded 32 n= 49 The command would look like this: CHR$(27);“!“.

64 return. Each time the printer receives a CHR$(13) it returns the print head to the left margin. It does not advance the paper (if DIP switch 2-6 is on; see below). Line feed is more complicated. Each time the printer receives a CHR$(lO) it both advances the paper one line and returns the print head to the left margin, ready to start a new line.

PAGE CONTROL Now that we have seen how to control line spacing, we can go on to page control - positioning the printing on the page and ad- justing the paper length. n Form feed The simplest forms control code is the form feed. Form feed (or (FF)) is CHR$(12) and causes the printer to move the paper to the top of the next sheet.
72 n Reverse form feed Just as your printer can perform a reverse line feed, it can do a reverse form feed. This code moves the paper so that the print head is positioned at the top of the current page.
73 Let’s set up a 7 inch high form length, which is typical of many computer checks. The following program will do it. NEW 10 ' Demo of variable form lengths 20 LPRINT CHR$(27);"C";CH.
Table 5-5 Top and bottom margin commands Function Control code Set top margin to n lines (ESC > “r” CHR$(n) Set bottom margin to n lines (ESC) “N” CHR$(n) Cancel top and bottom margins (ESC) “0” In both cases the value of n tells your printer how many lines to skip, although there is a slight difference in the usage.
75 Now when you run the program, your printer skip the first six lines and the last six lines on each page. 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.
76 SETTING LEFT AND RIGHT MARGINS The left and right margins of this printer work just like a typewriter - once they are set all printing is done between them. You can set margins either by using the keys on the con- trol panel, as described in Chapter 3, or by escape commands.
77 Run the program. The results will look like this: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxx When you want to reset the margins to the default values, you have two choices.
78 ONE TWO THREE FOUR Even though the words are different length, they are spaced out evenly by the horizontal tabs. Now add the following line to your program to set different horizontal tabs: 15 LPRINT CHR$(27);"D";CHR$(7);CHR$(l4);CHR$(21); CHR$(O); .

H Vertical tab channels Vertical tab channels are especially hefpful in two situations. The first occurs when you are writing a program to accompany a preprinted form that can accommodate verious types of responses. The second occurs when you create a multipage form or report with different vertical tabs on each page.

Printer’s bell l Master reset l Uni-directional printing l International character sets l Printing BIG characters l The optional sheet feeder l Reading a hex dump In the previous chapters we have learned about several groups of control codes.
88 - The code to sound the “bell” is CHR$(7), which is ASCII code 7 or (BEL). Any time your printer receives this code it will sound the bell for a quarter of a second. This can be used to re- mind the operator to change the paper or to make other ad- justments to the printer.
89 sheet. You can disable the paper-out detector so that it doesn’t stop the printer. This will allow you to print to the end of the sheet, and even beyond if you are not careful. The codes to con- trol the paper-out detector, along with the other codes that we have just looked at are in the following table.
90 The following program shows how these codes works. 127); lo LPRINT "BACKSPACE DOES NOT"; 20 LPRINT CHR$(8);CHR$(8);CHR$(8); 30 LPRINT u=== WORK" 40 LPRINT "DELETE DOES NOT".
. ‘ . L. at the speed of your typing. In the immediate-print mode, the print head prints one character at a time, as you send it. The printer also moves the paper up so that you can see the current line and then down to continue printing. You can turn the immediate-print mode on with (ESC) “i” 1.

93 CPS with the LQ characters. The main advantage to half-speed printing is a quieter run. n Uni-directional printing Uni-directional printing means printing in one direction only. Your printer normally prints when the print head is moving in both directions.
94 Let’s analyze the program. Line 20 defines the line spacing to 6/60 of an inch so that the characters that we print will touch top to bottom. Lines 30 - 50 print 10 vertical line characters. Then line 70 sets uni-directional printing and the vertical lines are printed again.

97 Figure 6-l shows what this program will print. If your chart doesn’t look like this because it has regular letters and numbers instead of the special symbols, then your computer is only using seven bits (unless you have set Standard mode by mistake).
98 In this program, line 10 selects character set #2 so that all the graphics characters can be used (including the “club” symbol). Then lines 20 - 80 print the 5 of clubs figure. Line 90 cancels character set #2 (which is the same as selecting character set #l).
99 The characters that change are shown beneath their ASCII code in Table 6-6. Table 6-6 International character sets H Printing characters in the control code area When you refer the Appendix C, you’ll find many characters are printed in the control code area.
100 In this program line 20 determines that the following 32 characters should be printed as printable characters. So, the characters in the control code area are printed as shown below. v+i4 irtj + 0 If you want to print more characters using the (ESC) “” command you must tell the printer how many characters should be printed.

102 THIS IS DOUBLE SIZED PRINTING. THIS IS QUAD SIZED PRINTING. As you can see, when the big character command is used, the baseline for each character does not align.
! 1: 103 cut sheets automatically. Work done on cut sheets looks better that done on computer paper, and you don’t have to tear the “perforations” off each sheet as you must with fan-fold paper. The automatic sheet feeder feeds a new sheet automatically every time the printer receives or generates a form feed.
104 10 FOR I=0 TO 255 20 LPRINT U-IRS(I); 30 NEXT I 40 LPRINT 50 END If your system passes the codes directly to the printer without changing them, you will get a printout like this.

105 Notice that your printer receives decimal code 13 (hex OD) together with hex OA, which is really decimal 10. In addition, your printer does not receive decimal code 26 (hex 1A). Your printer prints 16 hex numbers per line, printing the characters on the right hand side.

of the character itself and the spaces around it, you can actually create proportional width characters that print at draft speed. When defining draft characters, the number of printed col- umns (ml) cannot exceed 9, and the sum of m0 + ml + m2 can- not exceed 12.
I h L. i 113 character. You can send the character with the same ASCII value. You can also access the character from a BASIC program with the CHR$ function. In our example, we’ll assign the car a value of 60, which is the code for the character “(” in the ASCII characters.
characters (m0, ml and m2) are used to specify the width of the character and the space to be allowed on either side of it. The left space (in dot column) is specified by m0 and the right space is specified by m2. The second byte (ml) specifies the number of columns of dots that will be printed by the character.

- In the example program above, before we defined the new characters, we selected the Draft print mode. By doing this, we caused user-defined characters to print as draft characters because user-defined characters assume the mode that is in ef- fect at the time they are defined.
