This test prints across the entire width of the carnage. It
is agood idea to make sure that the printer is loaded
with the widest possible paper available to avoid the
possibility of damage to the print head or the platen.
This test can generate many lines of text and graphics,
so it is agood idea to use continuous fanfold paper
rather than single sheets. The test continues indefinitely
until the printer is turned off.
Printing out ahexadecimal dump
If you are writing your own programs to send output to
the printer, it is sometimes useful to print out the raw
data that the printer is receiving.
When you perform ahexadecimal dump, all codes (char-
acter codes and control codes) are printed out in hexa-
decimal format. The printer does not execute any of the
normally executable codes it receives (such as OA-line
feed). It simply prints them out.
Perform ahexadecimal dump as follows:
●Turn off the printer.
●Turn on the printer while holding down the [=]
and [FXWQkeys. The printer beeps once.
●Begin printing from your computer. Instead of anor-
mal print-out, data will be printed in sixteen col-
umns (two groups of eight) of hexadecimal numbers.
The equivalent printable characters, or dots for
unprintable codes, are printed to the right of each
row of hexadecimal numbers.
