proper emulation of successive print jobs, the printer must be able to identify the end
of job for each job.
Therefore, unless a wait timeout (the amount of time the printer is waiting on data from
the host) occurs and ends each print job, or unless you add an EOD command
between each file being printed through these protocols, some print jobs may be inter-
preted by the printer as one job and may “run” together. See chapter 2, “Printer Con-
figuration,” for more information on emulation timeout.
When printing multiple jobs with little or no time delay and with no EOD command
between each job, the serial and parallel protocols may be unable to detect an end of
job automatically. So the End Job Mode feature on QMS Crown printers was designed
to allow you to set the end of document for print jobs being sent through these
protocols.

If you are printing via the serial and parallel protocols, and one of the following condi-
tions exists, you may need to set the end job mode:
 Multiple print jobs with little or no time delay and with no EOD commands have
been sent to the printer and the message window displays only one active job.
 Multiple print jobs of the same printer language have been sent to the printer and
they print on the same page. (For example, you send the AUTOEXEC.BAT file
with no EOD command followed with little or no time delay by the CONFIG.SYS
file, and they both print on the same page.)
 Multiple print jobs of different printer languages “run” together as if they are a sin-
gle print job. (For example, you send a PCL print job followed by a PostScript print
job, and the PCL job prints and is followed by what appears to be program code
instead of your PostScript print job.)
 You want to print multiple jobs with header pages.
 You want to print multiple jobs where job separation is important.
When your printer is in ESP mode, printing multiple jobs through the serial and parallel
protocols and end job mode is not set, ESP technology interprets the emulation for
only the first job. The print jobs that follow are interpreted as being the same emula-
tion as the first job. For example, if there are two print jobs, the first a PCL file with no
EOD command, and the second a PostScript file with a Ctrl-D (a PostScript end-of-file
character)—ESP technology interprets the emulation of the first job correctly. But
