Printronix P9000 Series - Manual (Page 36)

Operation 2-18
For additional printing capabilities and character attributes, refer to the Programming chapĆ
ter. Print mode control from the host will override the control panel setting.
Setting Line Spacing
P9012 printers can be set for a line spacing of 6, 8, or 10.3 lines per inch (lpi) from the control
panel by using the 6/8 LPI switch. To select the line spacing from the control panel, perform the
following procedure.
1. Place the printer off line.
2. Press 6/8 LPI; the currently selected lpi setting will be displayed.
3. Press NEXT, PREV, or 6/8 LPI to step through the 6, 8, and 10.3 lines per inch selections.
The light beside the 6/8 LPI switch lights when the selected line spacing is other than 6 lpi.
4. Press CLEAR when the desired line spacing setting is displayed; the printer will be placed
off line and the display will read OFFLINE READY.
5. Place the printer on line.
Line spacing can also be selected by sending line spacing control codes from the host computer
as described in the Programming chapter. Using control codes, the host computer can specify
line spacing other than 6, 8, or 10.3 lpi. Line spacing control from the host computer will overĆ
ride the control panel setting.
Printer Reset
This procedure resets the printer to the configuration values last saved (not factory default valĆ
ues), and the current form position becomes the top-of-form. The printer can be reset to the
power-up configuration values at any time: on line, off line, or while printing. However, it is
recommended that the printer be reset only when off line to prevent the possible loss of data.
To reset the printer, press CLEAR and RUN/STOP simultaneously.
Hex Code Printout
The hex code printout (often called a hex dump") are useful for debugging when
troubleshooting printer data reception problems. Hex dumps list ASCII character data reĆ
ceived from the host with the corresponding two-digit hexadecimal code. Printable characters
print their assigned symbol; nonprintable characters are indicated with a period symbol. A p"
before the hex code indicates an active Paper Instruction (PI) line; a blank space before the hex
code indicates an inactive PI line. To print the data stream received from the host computer in
hex code with ASCII character equivalents, perform the following steps.
1. Place the printer off line and raise the printer cover.
2. Press MENU DOWN; repeatedly press NEXT or PREV until DIAGNOSTICS is disĆ
played.
