Overview
After the printer enters hexdump mode, all characters it prints (including any
in the printer's input buffer) are printed in two forms: as a two-symbol
hexadecimal code and as the character's printable symbol (if it has one). A
non-printable code is printed as a period [.] symbol. Up to 16 characters can
be printed per line of hexdump printout. While the printer is in hexdump mode,
it does not act upon any control codes, other than to print their hexadecimal
equivalents.
The 16 characters printed per line on the hexdump are formatted so that the
16 printable symbols are printed in columns 1 through 16. The 17th column is
blank. Column 18 contains either a p (PI line active) or a blank (PI not active).
Columns 19 and 20 contain the hexadecimal code for the first character,
followed by a blank. The PI line condition and hexadecimal code for the
second character are printed in columns 22, 23, and 24, followed by a blank.
The third through 16th characters are printed in a similar manner. The
hexadecimal code for the 16th character is printed in columns 78, 79, and 80.
NOTE: Values will vary based on printhead width.
Subsequent printing observes the current setting for skip-over perforation,
form length, and top-of-form position parameters.
IMPORTANT
You must have a minimum of 4.1 inches of media installed and have
Label Width set to 4.1 inches. If not, the hexdump data will be truncated
and lost.
If a fault occurs while printing a hexdump, the printer reverts to the normal
fault state. When the fault is cleared, the printer resumes printing the
hexdump (either a partial line with a form feed or nothing at all). Top-of-Form
remains unaffected.
Figure 6. Sample Hex Dump
To begin a hex dump, first place the printer offline and enable the Hex Dump
Mode option from the control panel. Next, place the printer online. Finally,
send data to the printer from the host computer. Any data received from the
host is "dumped" to the printout.
To cancel a hex dump, first place the printer offline. Then, disable the Hex
Dump Mode option from the control panel. The paper may then be advanced
to the next Top-of-Form.
The options are Disable (the factory default) and Enable.
