Stay in panel style
If held down during power-up, the (STYLE) button prevents software inter-
ference with the font style selected from the control panel. There will be an
acknowledging beep, after which you can set the printer off-line, select a
font style, then return to the on-line state and start printing. The selected font
style will not be changed by any commands sent by software.
Stay in panel pitch and style
If you want to protect both the pitch and font style settings from software
changes, press the(PITCH)and (STYLE) buttons during power-up. There will
be a little long acknowledging beep.
Pressing these buttons during power-up does not prevent you from making
any number of changes later from the control panel.
Hexadecimal dump
This feature is useful for programmers who are debugging printing pro-
grams and want to see the actual codes the printer is receiving. (Some
computers change the codes the programmer intended.)
In this mode, all received data will bc printed in a hexadecimal dump format,
rather than the control codes being acted on as command codes.
This mode is accessed with the following procedure:
1. Holding both me (PAPER FEED) and ( sE~%$~~ ) buttons 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.
3. At the end of the hexadecimal dump, set the printer off-line with the
( ON LINE Ibutton. This is necessary to print the last line.
