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. 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. Each time a dot is supposed to print an electromagnet inside the printhead causes the appropriate wire to strike the ribbon (making this printer an impact printer).

THE PRINT MATRIX

All of the standard characters that this printer prints are form- ed from patterns of dots that are permanently stored in the printer’s ROM (read-only memory). This includes all of the standard ASCII characters, and special characters, the interna- tional character sets, and the LQ characters.

The command ESC“A”CHR$n defines the line spacing as n/60 of an inch the ESC“2” command changes the line spacing to the amount defined by the previous ESC“A”. The loop that is started in line 20 increases the value of n the variable I in the program each time it is executed. So the line spacing increases as the pro- gram continues. Line 30 shortcuts the loop when I = 13, since BASIC won’t let us send CHR$l3 without adding an unwanted CHR$lO to it. Finally, the ESC“A”CHR$lO and ESC“2” commands in line 80 reset the line spacing to 6 lines per inch IO/60 or l/6 inch The results are the same as previous one n Moving down the page without a carriage return 40 ’ One-time reverse line feed 50 LPRINT CHR$27“j”CHR$lOO OI IOI ESC“N”CHR$n 20 ’ Leave 6 blank lines at the bottom of page 30 LPRINT CHR$27NCHR$6 50 FOR I=1 TO 60 LPRINT THIS IS LINE1 70 NEXT90 LPRINT CHR$lZ Form feed 100 END 80 LPRINT CHR$270 Clear bottom marginTHIS IS LINE THIS IS LINE THIS IS LINE I THIS IS LINE THIS IS LINE Try setting the margins with this program HORIZONTAL AND VERTICAL TABS When you run the program now it produces this Absolute horizontal tab Relative horizontal tab Vertical tabs have the same kinds of uses that horizontal tabs Try thisprogram tosee how this worksn Vertical tabs 10 ’ Demo of vertical tabs 40 LPRINT CHR$11 “FIRST TAB.” 80 LPRINT CHR$llFIFTH TAB W Vertical tab channels CHRSO120 LPRINT “2ND TAB OF CHANNEL’ 130 LPRINT CHR$12 140 NEXT MEMO CHAPTER SPECIAL FEATURES OF THE PRINTERPrinter’s bell Master reset Uni-directional printing Subjects we’ll cover in Chapter 7 includeYou can try this by typing n Backspace, delete, and cancel text Here is what this program will print Now add this line This command can be used to produce micro-justification 10 ’ Uni-directional printing 20 LPRINT CHR$27“A”CHR$6 power on condition 10 LPRINTCHR$270 20 LPRINTCHR$276 30 FOR J=3 TO 164 A 134 a159 f 169 c15 LPRINTCHR$27 95 LPRINTCHR$27= Double-highenlargedprint ESC“h”CHR$l DOUBLE ESCCHR$25 CHR$l or “1” THIS IS QUAI SIZED PRINTINGESCCHR$25 CHR$4 or “4” ESCCHR$25“R” or “R”10 FOR I=0 TO 30 NEXT 40 LPRINT 50 ENDPage Subjects we’ll cover in Chapter 8 include CREATING YOUR OWN CHARACTERSCHAPTER Designing your own characters Printing your own charactersTHE PRINT MATRIX O0 O0 O0 O0 O0 O0 O0 O0OO OO design and download into the printer.
