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. The total number of characters is equal to nl + (n2

x 256).

For example, if you want to print 300 characters, nl = 44 and n2 = 1 (300 = 44 + 1 x 256), the control code will be the following:

(ESC) “\” CHR$(44) CHR$(l)

There is one more command to print a character in the control code area: (ESC) “ A” n. This command prints one character determined by the value of n. You’ll get the same results as shown above with the following program.

40 LPRINT CHR$(I);

50 NEXT I

60 LPRINT

A note for IBM-PC users:

When you run these programs, you cannot get the right- pointed arrow (CHR$(26)) with the IBM-PC computer. This is because the IBM-PC does not send this code to the printer.

To avoid this problem, change line 40, and add line 100 and 120 to either of the following lists.
