4 To get at these, remove the printer cover from the printer. Then remove the screws with a Phillips screwdriver as shown in Figure l-4. You’ll be smart to save these screws, along with the rest of the packing material and the shipping carton, in case you ever have to ship the printer.

6 3. Using the guide holders as a fulcrum with the ribbon fac- ing away from you, as shown in Figure 1-5, lightly press the cartridge down until the two holder springs snap shut to hold the cartridge firmly in place. 4. Check that the cartridge fits so that the drive pins engage the cartridge teeth.
I ,I:, 7 Up to this point, we’ve been clearing the decks for action, so to speak. There are only a couple more things left to do before we can start printing - install the interface board and the font cartridge. W Installing the interface board I I Interface cover Interface board Figure 1-8.
8 n Installing the font cartridge This printer is mounted the Prestige characters as standard. You can add two different character styles by installing the op- tional font cartridges to the printer. To install or change a font cartridge, start by turing off the power switch.
CHAPTER 2 GETTING TO KNOW YOUR PRINTER Subjects we’ll cover in Chapter 2 include - l Parts of the printer - what they’re for and how to use them; l Paper selection and loading; l Adjustment; l Testing printer operation. CONTROLS AND PARTS OF THE PRINTER W Parts of the printer First, we’ll go over the parts of the printer.
Mute cover Printer cover Font cartridge slot ’ Interface cover L Figure 2-1. Front and rear views of the printer. INTERFACE COVER - On the back of the printer, this con- ceals and protects the interface board. The cover is cut away to expose the external connector to which you attach your com- puter cable.
11 SLOTS FOR FONT CARTRIDGES - These are the two openings at the bottom right of the front of the printer. Insert- ing an optional font cartridge pushes the small door up out of the way and exposes a connector which accepts the cartridge.
TOF KEY - Ejects the current sheet, feeds a new sheet, and moves the print head to the left margin. PAPER FEED KEY --Advances the paper one line at a time when the On Line indicator is off. If you hold the key down, you can get consecutive line feeds, one after the other.
foration skipping. See Appendix A for a complete list and ex- planation. SELECTING AND LOADING PAPER Your printer can handle the two basic types of paper - single sheets (stationery, envelopes, multipart business forms, etc.) and continuous paper (fan-fold perforated paper).
n Loading single sheets Now, instead of feeding the paper in manually by turning the platen knob, we’re going to use the release lever for automatic feeding (the printer must be turned on). Single sheets from 5.5 to 14.5 inches wide can be used. OK? Let’s start.

Let’s see how to use compressed printing with SuperCalc. In SuperCalc, the /Output command provides out put to the printer.
cessor handles it. Once you understand the concept you should be able to use your program manual to figure out how your word processor does it. The program that we will study is‘the EasyWriter word pro- cessor for the IBM Personal Computer. This uses a fairly typical method of handling special codes.
32 MEMO.
Subjects we’ll cover in Chapter 4 include- * Listing BASIC programs on the printer; l Printing from BASIC; l CHR$ function; l Command syntax; l Problem codes. In this chapter we will be teaching you how to use your printer’s features using the BASIC programming language.
c LPRINT things other than character strings. We started with Microsoft BASIC because it is the most wide- ly used version of BASIC around. The programs in this manual are written in Microsoft BASIC so they should run on most com- puters.
35 BASIC program. Generally, computers use about the same pro- cedure for printing in a program as they do to list a program. Let’s try what we learned. Type the following: NEW 10 LPRINT "TESTING" RUN Remember-we use LPRINT; you may have to use something else! At any rate, you should have the word “TESTING” on your printer.
36 Where did that noise come from? That’s the printer’s bell. We will learn more about it in Chapter 5. We just wanted to il- lustrate a code that causes the printer to perform a function.

38 MEMO.
CHAPTER 5 PRINTING TEXT Subjects we’ll cover in Chapter 5 include- * Letter quality (LQ) characters; l Underlining and overlining; l Superscripts and subscripts; l Print boldface; l Print pitches. The rest of this manual will show you a little BASIC - just enough for you to use your printer.
40 printing, for it takes a keen eye to detect that it is from a dot matrix printer. Normally, your printer prints draft quality characters when the DIP switch 1-4 is set off. This is adequate for most work and it prints fastest. But for the final printout, try Letter Quality.

46 Demonstration of EXPANDED printing. Notice that EXPANDED mode automatically turns off at the end of a line. Expanded print set with CHR$(14) is automatically cancelled at the end of the line. This is convenient in many applications, such as for one line titles.
I / ? :’ 47 n Condensed print Each of the print pitches also can be condensed to its normal width. This is called condensed print. Try this program to see how it works: 10 ’ Demo of condensed pitch 20 LPRINT "Demonstration of "; 30 LPRINT CHR$(15); 40 LPRINT "CONDENSED"; 50 LPRINT CHR$(lS); 60 LPRINT w printing.

49 Table 5-9 Proportional commands Function Control code Proportional ON (ESC)“p”l Proportional OFF (ESC)“p”O Try this program to see how the proportional spacing works. 10 ’ Demo of proportional printing 20 LPRINT CHR$(27) ; “~1”; 30 LPRINT “This line is PROPORTIONAL printing.
50 Here, the value of n defines the print style to be selected. The value of n can range from 0 to 255, which is the range of values that can be stored in one eight-bit byte. If you look at each bit in this byte, you’ll find that each one represents a printing style variation.
51 For example, suppose you turn on both Proportional and Con- densed modes. Since these cannot combine the printer must make a choice; in this case, the printer chooses Proportional. Summary notes 1) Pica is the default pitch and is active when Elite is turned off.

- CHAPTER 6 FORMATTING TEXT Subjects we’ll cover in Chapter 6 include- * The carriage return and line feed; l The amount of space between lines; l Moving to the next page; l The number of lines on a printed page; l Horizontal and vertical tabs; l Setting margins- left, right, and bottom.
54 print head to the left margin, ready to start a new line. Now to add a little confusion-most (but not all) versions of BASIC add a line feed (CHR$(lO)) to every carriage return (CHR$(13)) that they send. If your version of BASIC doesn’t do this, then you should turn DIP switch 2-6 off so that your printer will add the line feed for you.

56 When you are using your printer with the DIP switch 2-2 off, the (ESC)“A”CHR$( ) n works to change the line spacing without (ESC)“2”. So in this case, change the following lines as shown below: 40 LPRINT CHR$(27);"A";CHR$(I); 80 LPRINT CHR$(27);"2" The results are the same as previous one.

58 The (ESC)“J”CHR$(lOO) in line 50 changes the spacing to 100/180 inches for one line only without moving the printhead. The rest of the lines printed with the normal line spacing. Notice that both line 30 and line 50 end with semicolons. This prevents the normal line feed from occurring.

This program should print “PAY TO THE ORDER OF:” twice, and they should be 7 inches apart. Line 20 sets the form length to 7 inches. After line 30 prints, line 40 sends a form feed advance the paper to the top of the next form. Line 50 then prints its message.

64 on, or you can set margin values equal to the default values. This means that you should set a left margin of 0 and right margin of 136 in pica pitch. If you change the pitch of your printing after you set your margins, the margins will not change.
65 , . 15 LPRINT CHR$(27);“D”;CHR$(7);CHR$(l4);CHR$(21); CHRS(O) ; (ESC)“D” is the command to begin setting horizontal tabs. It must be followed by characters representing the positions that you want the tabs set. In our program we are setting tabs in col- umns 7, 14, and 21.

68 set at line 20, a vertical tab (or <VT>) will move you to line 20 whether you start from line 5 or line 19. The vertical tab is not set at the power-on default. If you send a CHR$(ll), which is the ASCII code for < VT > , before we have set up tabs advance the paper one line.
69 Add one more line to the program to demonstrate one more feature of vertical tabs. 80 LPRINT CHR$(ll):"FIFTH TAB." Now when you run the program the first page looks just like before, but line 80 sends one more <VT > than there are tabs.

Most BASICS, however, are not quite that straight forward. For example, the IBM-PC prints like the following. Notice that your printer is receiving decimal code 13 (hex OD) is coming with hex OA, which is really decimal 10. In addition, your printer does not receive decimal code 26 (hex 1A).
CHAPTER 8 CREATING YOUR OWN CHARACTERS Subjects we’ll cover in Chapter 8 include- * Designing your own characters; l Printing your own characters; l Print mode and the download characters. In the previous chapters of this manual you’ve learned how to control the printer to give dozens of different typefaces.
90 - Figure 8-1 shows an enlarged schematic view of the front of the printhead, showing the ends of the wires and their relation- ship to the draft characters. As you can see, the capital letters use the top eighteen wires of the printhead, and the descenders (such as the lower case “p” shown) use the bottom eighteen pins.
91 But there is another area of memory in this printer reserved for user-defined characters. These are characters that you can design and download into the printer. When download characters are defined they are stored in RAM(random access memory), which allows you to define or modify them at any time.
92 the same way. Make up some grids (photocopy Figure 8-3 if you wish) and get ready to be creative! (Just in case you are not feel- ing creative, and to make our explanations a little clearer, we’ll be using a picture of an automobile as an example of a draft download character.
1 123458789 128 64 32 1st 18 byte 8 4 2 1 I 128 84 32 4 2 1 ASCII Data code: 2nd 18 Left space: We 8 Right apace: 128 1st: 84 32 I 8 2nd: 3rd: 3rd 18 4th: byte 5th: 4 8th: 2 7th: 1 8th: 9th: Figure 8-4.
94 dots, the printhead would have to slow down and back up to print both dots-not very efficient! To avoid this inefficiency, this printer will not allow you to define a character like Figure 8-5. (Actually, you can define it, but when it prints, your printer will leave out the overlapping dots, so that it would print like Figure 8-4.
95 which we’ll get to shortly. 1st byte 2nd bvte r 3rd byte 123456769 d3zEl 126 64 32 16 6 4 2 1 126 64 32 16 6 4 2 1 126 64 32 32 16 16 6 6 4 4 2 2 1 1 ASCII code: 66 Left *pace: I Right space: 2 Figure 8-7. Add the values of the dots in each column and write the sum of each column at the bottom.
96 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. n Assigning a value to your character We’ve done a pretty through job of designing and describing a user-defined character.
for user-defined characters, but a caution is in order. Characters with ASCII values below 32 are usually reserved as control codes by both your computer and your printer. While these characters can be replaced by user-defined characters, it should be avoided because of the effect on the normal control codes.
! 98 You’ll probably recognize dl d2 . . . . dx from the top of our layout grid. That’s right, each column is described by three bytes. Now we’ve got everything we need to download one character to the printer.
99 When you run this program, it looks like nothing happens. That’s OK. We’ll see why in just a moment. Save this program. We’ll need it again shortly.
50 LPRINT 60 FOR I=160 TO 254 70 LPRINT CHR$(I); 80 NEXT I 90 LPRINT 100 LPRINT CHR$(27) ;“;%O”;CHR$(O) 110 END Nope! Just two characters in the download set. This is inconve- nient for a couple of reasons. First, every time you wanted to use a download character you would have to switch back and forth between character sets.
To demonstrate how to use these characters, let’s use this character set to print a small graph. This program, which has been built around the first program in this chapter, will do just I that: 10 .

103 Note that we didn’t hnvc to re-enter the download characters, since they were already sent to the printer with the first pro- gram. They will stay with the printer until you download new characters to replace them or turn the printer off.
104 THE PRINT MODE AND THE DOWNLOAD CHARACTERS 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.
