Output performance considerations
The LPS has a rated speed of up to 50 (4050, 4450, and 4650) or
up to 92 (4090) impressions per minute (an impression refers to
one printed side of a sheet of paper). The actual output
performance you experience depends greatly on the processing
features invoked in the job and the print density of each page.
Actual output also varies according to the configuration of the
LPS, such as the type of connection (offline, online, remote
communication, and front end processor).
This section provides information on expected output
performance when printing various types of jobs, applications,
and hardware configurations. For more detailed information,
consult your service representative.
Note: The term throughput refers to the print speed once pages
start printing. The processing that occurs prior to the actual
printing of the pages depends greatly on the complexity of the
job.
Interpress Interpress masters sent to the LPS must be processed by the
Interpress decomposer function of the Operating System
Software (OSS). The time required to print an Interpress job
depends on the complexity of the image from page to page.
PostScript PostScript masters sent to the LPS must first be converted to
.IMG files in the front end processor. The time required to print
a PostScript job depends on the complexity of the image from
page to page.
Dynamic Job Descriptor Entries (DJDE) The use of DJDEs adds processing time and slows the output.
To maximize performance, restrict the use of DJDEs to the
following commands: GRAPHIC, FORMAT, MODIFY, and FORM.
