Description This command allows characters from 0 to 31 codes to be printed. During
normal operation, characters from 0 to 31 are control characters. This
command turns off the control code translation for the following character. <n>
can be from 0 to 255.

The mapping of a print pattern to each character address is referred to as a code
page or character set. At any given time, the printer character set is comprised
of 256 characters. Each character is addressed by an 8-bit value generally
referred to as a character code. For example if you want to print an ‘A,’ the
character would be addressed by sending a <65> decimal to the printer. There
are 65 predefined code pages or character maps that assign characters to a
particular address built into the printer. However, there are times when an
application would like to redefine a character or group of characters in a code
page. To be able to redefine characters, the Series 90PLUS Printer allows the
map for any code page to be replaced. The “Define Character Set” command
allows any character or group of characters to be replaced with any other
printable character. There are over 500 printable master characters defined in
the printer.

The internal character map is provided in the Master Character Set Definitions Guide (PN 100-9785).
