To turn off the data dump mode and stop printing, press
ON LINE
to set the printer off line. (If you press
ON LINE
while a page is being printed, the green
ON LINE
light
flashes until the page is ejected and the printer goes off
line.) To exit the data dump mode, turn off the printer or
hold down the RESET button until INITIALIZE appears on
the display.
Look at the sample data dump printout shown in Step 3. By
reading the characters printed in the text field on the right side
of the data dump printout or the printout of hexadecimal
codes, you can check what codes are being sent to the printer.
In the text field, printable characters appear as their true ASCII
characters. Non-printable codes, such as control codes, are
represented by dots.
For example, look at the first two hexadecimal codes on line
0006 of the printout sample
(74
65). Code 74 represents the
letter t; code 65 represents the letter e. Check the seventh line of
the text field on the right side of the printout and you will find
the letter t followed by the letter e.
