Testing Printer-
to-Host
Communication
QMS magicolor CX User's Guide 4-46
c Reboot the PC and try the communication test again.
If the printer repeatedly fails to complete this test, refer to
your DOS documentation for more information.
Serial Test
1 Go to the DOS C:\ prompt.
2 At the DOS C:\ prompt, send PRINTEST.PS to the printer by
typing the following command:
print printest.ps
↵
If prompted for the name of the list device, type the name of the
serial port you're using at the computer, for example,
com1
↵
» Note: If the computer has more than one serial port, they're
probably labeled. If not, check the computer documentation for
the COM port names.
If a blank page ejects from the printer, the printer and the com-
puter are communicating.
If a blank page does not eject and you typed the file correctly,
make sure the printer's serial port settings match those of the PC.
See “Checking Serial Communication Settings,” below.
Checking Serial Communication Settings
If the serial communication test described above doesn't work, then
make sure your printer's serial port settings (baud rate, parity, data
bits, and stop bits) match those of the PC.
To find out what the PC's serial settings are, look in your
AUTOEXEC.BAT file (in the root directory) for a command line like
this:
mode com1:9600,n,8,1,p
In this example, the PC's serial port communication settings are 9600
for baud rate,
n
(no) parity, 8 data bits, and 1 stop bits. The
p
stands
for infinite retry.
