This test prints across the entire width of the carriage. It
is a good 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 a good idea to use continuous
fanfold paper
rather than single sheets. The test continues indefinitely
until the printer is turned off.
Printing out a hexadecimal
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 a hexadecimal
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 a hexadecimal
dump as follows:
.
Turn off the printer,
.
Turn on the printer while holding down the [FONT]
and [PAPER) keys. The printer beeps once.
.
Begin printing from your computer. Instead of a nor-
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.
