Section 6: Solving Problems
Axis AFP User’s Manual 55
Low Printing Speed If loaded fonts are used, check that the free VM Size is at least 700 kbytes, and that
parameter #3001 is set accordingly.
Coax: You can also consider to use printer resident fonts instead. This is defined in PSF/
MVS using the APSRMARK utility and in PSF/VM using the APRFTBLV
(RSCS) or APRFTIDB files.
If large overlays, page segments, or fonts are used, they can be kept in the printer
between jobs, avoiding to down-load them for each job. This can be done using
the APSUX07 PSF exit.
Twinax: If you only run applications that do not require AFP functionality, consider set-
ting [AFP = *NO] in the AS/400 device description to speed up word process-
ing printouts. Note the limitations described in Section 2.3.
If you are using AFP functions (with [AFP = *YES]), try the following:
• Assign more memory to [QSPL]. Run [WRKACTJOB] to see which pool
[QSPL] uses, then run [WRKSYSSTS] to set the new memory size. The
recommended size is 2 Mbytes (80 kbytes is the default size).
• Lower the number of simultaneously active print jobs in the QSPL memory
pool. The recommended number is 3, but on larger systems a higher number
might be necessary. Run [WRKSYSSTS] to change this number.
• Disable Computer Output Reduction [*COR] if possible. This is selected in
the application printer file.
• Use [*IPDS] or [*AFPDS] as application data stream, rather than
[*SCS]. This is also selected in the application printer file.
The document "IBM AS/400 Printing II" (GG24-3704) gives more examples on
how to increase the AFP performance.
Note that the printing speed also depends on the performance of your PostScript
printer.
