Is the printer receiving data from the computer?
Is the printer on line? The message display should display
IDLE
, and the On indicator should be lit.
Has the interface port been set to a language or emulation 
that does not match the file you are sending?
If you are using the serial interface, is the baud rate (speed of 
data transmission) of the printer, the computer, and your 
application software the same? Print a status page from the 
control panel to check your printer setting.
If you still cannot identify the problem, contact QMS Cus-
tomer Technical Assurance.

Is the printer printing codes or not printing at all when in 
ESP mode? If one of these things is happening, check the 
following:
Reconfigure the port to the specific printer language of the 
file you are trying to print. See your system administrator.
If a PostScript file prints PostScript language statements 
while in ESP mode, increase the ESP timeout. (See the 
Sys-
tem Administrator's Guide for instructions.)
If you continue to have problems with the ESP mode select-
ing a printer emulation, contact QMS Customer Technical 
Assurance. See appendix A, “QMS Customer Support,” for 
information on customer support.
