ADC and MEt Notes
For raster graphics compression to perform at its best it is
recommended that the “Recommendations For Sending
Data to the Printer,” described below, be followed.
Character bitmaps can only be compressed if they can be
stored uncompressed in contiguous printer memory first.
This requirement implies that large point size characters
may require more printer memory than would seem
necessary.
During MEt’s Page Protection, portions of the internal
representation of the page are discarded to make room for
other aspects of the page protection process. If a memory
out condition occurs during this process (unlikely, but
possible) a white band will be seen on the page. The best
way to remedy this situation is to add memory to the
printer.
Recommendations
For Sending Data to
the Printer
The HP PCL 5 printers perform best in terms of speed and
memory utilization if the recommendations made below are
followed. Failure to follow these recommendations will not
harm the printer, but may increase the chances of a
memory out condition or increase the time to print a page.
Ordered Images — Raster Graphic images or pictures
should be sent from top to bottom with the data in one
band (start raster, end raster pair). If one band is not
possible, as few as possible multiple bands may be used
as long as they exactly follow each other and are sent in
top-to-bottom order. Also, multiple bands should be as
large as possible.
Band Sizes — If an image is sent in bands (start raster,
end raster pairs), the bands should be multiples of 32
lines high. This is especially critical for landscape
graphics. If there is no way to send multiples of 32-line
high bands, multiples of four for band height should be
used. This allows Image Adapt to work better.
