F. Memory Requirements and Recommendations
Additional memory above the minimum recommended may be required for printing DBCS characters,
TrueType fonts, complex mono or color IPDS jobs or if printer memory is used to save other emulation
resources or hold other emulation jobs for later printing. A minimum of 128 MB of memory is required to
activate DBCS printing.
TrueType fonts are downloaded to a different part of printer memory than other resources. Because
TrueType fonts can be very large, the space allocated to them is a maximum of 50% of the total printer
memory. Attempts to download additional fonts will result in a memory exception. True Type Font
support is only available on selected products that support IPDS code release 3.01-01210 and higher. For
some products this code may only be available as a field upgrade. Contact your point-of-purchase for
information.
In the tables below, you will see that some values apply when ”saving of IPDS resources” is activated.
Activation requires that the host timeout and printer IPDS Timeout values are properly set.
See
IPDS Timeout on page 29 for further information.
