Printing Hex Dumps

The HEX-DUMP function prints data and commands in hexadecimal
characters and abbreviated control codes. The IBM character set 2 is
used for printing (see Appendix E). The HEX-DUMP function is
useful for checking whether your computer is sending the correct
commands to the printer and whether the printer is executing the
commands correctly. It is also useful for debugging software pro-
grams.
