Short test pattern: On Line switch
If held down during power-up, this switch prints a short test pattern
(shown in Chapter 1).
Long test pattern: Paper Feed switch
If held down during power-up, this switch prints a long test pattern.
The test cycles endlessly. To stop the test you must switch power off.
Stay in pane/ pitch: Print Pitch switch
By holding this switch down during power-up, you can prevent software
interference with the print pitch selected from the control panel. You will
hear an acknowledging beep as power comes on. After the beep tone, you
can set the printer off-line, select a print pitch, then return to on-line and
start printing. The pitch you selected will not be reset or otherwise changed
by any commands your software may issue.
Stay in pane/ Sty/e: NLQ Type Style switch
If held down during power-up, this switch prevents software interference
with the type style selected from the control panel. There will be an ac-
knowledging beep, after which you can set the printer off-line, select a type
style, then return to the on-line state and start printing. The selected type
style will not be changed by any commands sent by software.
If you want to protect both the Print Pitch and NLQ Type Style settings
from software changes, press both switches during power-up. There will
be two acknowledging beeps.
Pressing these switches during power-up does not prevent you from
making any number of changes later from the control panel.
Hexadecima/ dump: Paper Feed and Print Pitch switches
This feature is useful for programmers who are debugging printing
programs and want to see the actual codes the printer is receiving. (Some
computers change the codes the programmer intended.)
1. Holding both the Paper Feed and Print Pitch switches down, turn power
ON. A beep tone will be heard.
2. Start printing. In place of the usual printout you will get a formatted
dump showing exactly what data the printer receives. Each line presents
sixteen characters, their hexadecimal codes to the left and printable
characters printed on the right.
