Hexadecimal dump mode
In this mode, all received data will be printed in a hexadecimal dump format,
rather than the control codes being acted on as command codes.
This mode is accessed by turning on the printer, while simultaneously
holding down the (+!K?%$ and (-1 keys. To turn off the mode, it is
necessary to turn off the printer completely.
The printout will be similar to that produced by a MS-DOS DEBUG Display
command, ie the hexadecimal values of the bytes received will be given in
rows of 16, divided into two blocks of eight. “Unprintable” characters, ie
control codes from OOh through 1Fh and 7Fh through FFh, are represented
by periods.
The following (BASIC) program will produce the result below it:
10 FOR I=0 TO 255
20 LPRINT CHR$(I);
30 NEXT I
40 LPRINT
50 END
After the program has been nm, the printer’s buffer should be flushed by
pmssing the (ZZC@C button.

This mode is useful when installing and debugging software, to ensure that
the characters and codes actually being received by the printer are those
which are actually required.
