Stay in pane/ pitch: Style/Pitch and Paper Feed switch
By holding these switches 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/ style: Style/Pitch and Quiet Mode switch
If held down during power-up, these switches prevent software inter-
ference with the type style selected from the control panel. There will be
an acknowledging 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 Type Style settings from
software changes, press only the Style/Pitch switch 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.
Hexadecimal dump: Paper Feed and Quiet Mode 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 Quiet Mode 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
1 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.
3. At the end of the hexadecimal dump, set the printer off-line with the
On Line switch. This is necessary to print the last line.
The followipg BASIC program is a simple test you can run in hexade-
cimal mode:
10 FOR I=0 TO 255
20 LPRINT CHR$(I);
30 NEXT I
40 LPRINT
50 END
