Appending small print jobs into a single large job
Under Printer Options is the ‘Concatenate Logical Reports’ option.
The Concatenate Logical Reports option is used to solve the problem caused by
DJDEs calling different JDEs in an incoming data stream.
A change of JDE causes PARIS to go into its ‘end of job’ processing loop. In
the case of a PostScript printer, this means that the resources are flushed and
have to be re-sent.
Each time the JDE changes, it also creates a new job entry on the printer. In
extreme cases where the JDE is changing on almost every page the result can
be hundreds or potentially thousands of small jobs being submitted to the
printer. This also means that with each new job the resources are re-sent to the
printer.
Why is the option necessary?
The combination of the above factors has a severe impact on printer
performance. To prevent both the continual reloading of resources and flooding
the printer with numerous tiny jobs, the Concatenate Logical Reports option is
used. This instructs PARIS to append small print jobs into a single large job.
 
To append small print jobs into a single large job:
Select the ‘Concatenate Logical Reports’ checkbox.
