Specifying print format parameters

Using LCDS Print Description Language
Example: Assuming that your application calls for 8.5
by 11-inch paper, you could use 5 pitch mode.
However, by selecting 4 pitch, which reduces the
pages per minute on the DP180 EPS from 180 to 77,
you make the printer speed more closely match your
finishing device capabilities and you reduce the
potential for paper jams.
Problem: Your application uses four paper sizes,
ranging from 8.5 by 11 inches for the first few
pages to 11 by 17 inches for the last several
pages. Each time your printer detects a different
paper size, it adjusts to accommodate it,
significantly reducing throughput time.
Solution: By specifying a low enough pitch mode to
accommodate all the paper sizes in your application
(in this case, 3 pitch mode), you make the entire job
run at the maximum possible throughput speed
because paper size adjustments are limited. Keep in
mind that you may select a lower pitch mode (allowing
a greater scan value) for smaller size paper, but you
would not want to select a pitch mode too small to
accommodate a larger paper size.
Problem: You want to estimate how many
applications you could run on a particular shift.
However, given the size and complexity of your
applications, you are uncertain as to how to plan.
Solution: By looking at the paper sizes, and thereby
the pitch modes required by each application and the
number of pages in each application, and by
associating these with the ppms provided in the
preceding table, you can roughly estimate the length
of time each application requires for printing.
There are no absolute rules and no set methods for
accomplishing your printing goals. The variables that are
involved include individual finishing device requirements, the
paper sizes required by your applications, the complexity of
each page, the number of pages in each application, and so
forth. However, a general understanding of the relationship
between paper size and pitch mode and the advantages of
specifying pitch modes will help you optimize your printing
activities.
