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.

You may wonder why they picked l/60 of an inch as the incre- ment for the line spacing command. There’s a good reason: the dots that the printer makes are l/l80 inch apart. So this means that you can vary the line spacing in increments as fine as three

dots - unless you want finer spacing, like one dot spacing.

The (ESC)“3”CHR$(n) command sets the line spacing in in- crements of l/180 inch. Change line 40 in your program so it is like this:

40 LPRINT CHR$(27):"3";CHR$(I);

and run the program again. Now the results will look like this:

INCH.

The program works just the same as before, but the line spac- ing are just one-third what they were. This is because (ESC)“3” CHR$(n) sets the line spacing to n/180 inch.

Table 6-2 shows all the line spacing commands, including several “shortcut” commands for commonly used line spacings.
