InfoPrint 3000 Operator's Guide
Description
Font usage allows you to select the amount of memory
that the printer control unit (computer) will use for font
management. Select the font usage according to the type
of print jobs you run.
Select Low font usage for jobs using a normal number of
fonts with normal point sizes, but not double-byte fonts.
Medium font usage indicates an abnormal single-byte
character set (SBCS) printing mode; select it for jobs
using a large number of fonts or very large point sizes,
but not double-byte fonts. High font usage is primarily
for double-byte font jobs.
This is used to allocate space for IPDS source for page
segments and overlays. Set to Low if the size or number
of page segments and overlays is a small. Set to High if
the size or number of page segments and overlays is
large.
This parameter is used to allocate space for a cache of
ready-to-print overlays. Set to Low if a few small
overlays are used. Set to High if many or large overlays
are used.
This parameter is used to activate or deactivate overlay
caching. Set to No if overlays are not reused multiple
times or if overlays are not reused in the same location
on subsequent pages.
This parameter is used to allocate space for the IPDS data
that was just received from the server before being
processed by the control unit. Set to Low if pages contain
little data or if printing from PSF/MVS on a System/370
channel or an ESCON channel (this is because of the
frequent IPDS acknowledgment rate). Set to High if
printing pages with large amounts of data (such as large
images).
This parameter is used to allocate space for ready-to-print
pages, including pages between the transfer points of a
continuous-forms, duplex printer. Set the value to Low if
these conditions are met:
v The pages contain little data
v This is a simplex printer
v This is a duplex printer with a distance between
transfer points of less than 400 inches.
Set the value to High if these conditions are met:
v The pages contain large amounts of data, especially
shaded areas
v This is a duplex printer with a distance between
transfer points of over 400 inches.
This entry shows if printing is to occur in direct-printing
mode when connected to an MVS or OS/390 operating
system, with no host-assisted recovery procedures such
as retransmission of pages after a forms jam.
The host system programmer will inform you whether
this entry should be set to Yes.
