PC DOS printing problems

Table 6-7 PC DOS printing problems

Image never prints.
Printer acts as if it is
receiving data, but
nothing comes out of
printer, or the printer
goes back to "Ready"
mode without printing
image.
Make sure that the computer is communicating with the
printer.
At the DOS prompt, type the following in lowercase letters:
echo showpage > port:
(substitute LPT1:, LPT2: or COM1, etc., for port: )
The printer responds by sending a page through the print
cycle and ejecting a blank page. If this does not happen,
check your cable, or try a different parallel cable. If using the
serial port, refer to the serial port configuration.
Ensure that the print file ends with a "CTRL-D" character.
CTRL-D indicates the end-of-file, which the printer responds
to by closing host-to-printer communications and then
processing and printing the file. Use a text editor to open and
examine the file. On-screen, a "CTRL-D" character appears
as a " " character.
Check and add, if necessary, the following line to the
AUTOEXEC.BAT file:
mode = LPT1,,p
(If your port is not LPT1, substitute LPT2: or COM1: for the
correct port). This turns on printer retry indefinitely.
Is the printer in PostScript mode? Check this by sending the
file TESTHPGL.PLT (located on the Tektronix Utilities
diskette, HP-GL directory) to the printer.
At the DOS prompt, type the following DOS command:
COPY TESTHPGL.PLT LPT1:
(If your port is not LPT1, substitute LPT2: or COM1: for the
correct port).
The PC responds with 1 FILE COPIED. If this file prints
stating that the printer is in HP-GL mode, then the printer
needs to be changed back to the PostScript mode. Use the
utility located on the Tektronix diskettes to change language
emulation. Refer to the Phaser 360 Drivers and Utilities
Printing Reference for complete instructions.
Enable the Error Handler from the front panel menu Printer
Defaults - Error handler. The printer now has a PostScript
error handler present which remains resident until power is
cycled on the printer. Resend the image file that was not
printing.
Any PostScript errors encountered by the printer are recorded
on a printout. Call Tektronix Customer Support at
1-800-835-6100 for more assistance (save the print with the
error message).
