PRINT FORMAT COMMANDS
6-104 XEROX DOCUPRINT 180 LPS PDL REFERENCE
Points to note
Note the following when using the PDE command:
• The maximum number of fonts that may be used in printing a
given page or a given job varies depending on a number of
factors. For both the input and output tasks, the number of fonts
specified in the FONTS parameter must be at least equal to the
largest number of fonts required to print any page within the job.
Particularly for the input task, the limitations of dynamically
allocated memory, (that is, when input is unable to receive an
allocation of dynamic memory, the job is aborted), impose
additional constraints which effectively reduce the maximum
number of fonts that may be used to print a page. The number
of fonts specified in the FONTS parameter is used to determine
the size of a dynamically allocated table where information
about the fonts is cached.
If the patch to enable the use of Merganthaler fonts is selected
when the LPS is sysgened, the use of dynamic memory for
fonts increases significantly since a proportionally spaced font
requires an additional 120-260 bytes of dynamic memory.
The maximum block length for an offline job can be a size such
that the allocation of one input buffer or two of equal size can
cause dynamic memory allocation problems when used in
conjunction with a large PDE FONTS parameter and with
Merganthaler fonts enabled.
• An xdot is 1/600 unit of measurement. A form specifying xdots,
however, can be created, edited, and compiled on any LPS with
version 3 software, but the form, which is 600 spots per inch
(spi), does not print on your 4050, 4090, 4635, or DocuPrint 180
which accepts only 300 spi.
