DOCUPRINT IPS SOLUTIONS GUIDE
When you print AFP documents that contain 240 pel images to
DocuPrint IPS printers set to run in 300 dpi mode, PSF converts the
IM images to IOCA image format. Using the Resolution option on the
DocuPrint IPS user interface, you can specify that the document print
at 240 or 300 dpi (or 600 dpi on DocuPrint 92C, 96, 180, 4635 IPS
systems).
The print quality of any images you currently use with AFP may
depend on how they were created originally. For example, you may
have created an image at 240 pel resolution but, when converted to
300 dpi, it may not look like it did originally. However, a different
image created at 240 pel resolution may look the same when
converted and printed.
The DocuPrint IPS printers use an algorithm to convert 240 pel
images to 300 dpi. To determine if this internal conversion will
produce the quality of output you require, print a test document to the
DocuPrint IPS printer. Look at the document to decide if the print
quality is as clear as you'd like it to be. If so, you may continue using
the image without making any changes. However, if the print quality
is not satisfactory, you should either regenerate or rescan the image
at 300 dpi.
Color IM-type images
If you are running PSF/MVS, you can print IM images in color to a
DocuPrint IPS printer as described in Table 4-1. If the IM resolution
and the printer resolution do not match, conversion by PSF strips the
color bit from the data stream.

1. "PGD units" is the page dimension structured field that indicates the
unit of measure for the page.
2. This column applies only to the PSF/MVS platform. Other PSF
platforms have not been tested.
3. 600 dpi resolution applies only to the DocuPrint 96/4635/180 IPS,
MIICR versions of these printers, and the 92C IPS.
