Virtual Memory Support
Your printer supports virtual memory capabilities for all of the memory
clients except Disk Cache and Frame Buffer when disk swapping is
enabled (Administration/Memory/Enable Disk Swap menu). These
capabilities extend the amount of memory available for certain sup-
ported features, such as spooling and collation.
End Job Mode
When sending print jobs through the serial and parallel protocols,
some applications and their printer drivers append an end-of-docu-
ment command (EOD) to each print job to ensure that each file prints
correctly. The reason for this is that some protocols and print queuing
systems send print jobs to the printer as one continuous data stream
(one print job immediately following another).
But the problem with this system is that some applications are limited
by the printer language and are unable to produce an EOD com-
mand. This becomes even more problematic when you’re printing to a
QMS 4060 Print System, where print jobs of all supported emulations
can be received simultaneously. ESP technology examines the first
part of each print job to determine its emulation. Once the emulation
is identified, the print job processes without further checking. This
minimizes any slowdown resulting from the sensing process. To help
ESP technology determine the proper emulation of successive print
jobs, the printer must be able to identify the end of job for each job.
