Printing Dbcs Characters - Lexmark X644E User Manual

E. Printing DBCS Characters
Several languages, such as Chinese, Korean, and Japanese, have fonts so large that it takes two bytes of
information to represent each character. These fonts are referred to as Double Byte Character Set (DBCS)
fonts. Depending on the language, the number of characters in the font can range from around 6,000 up to
approximately 22,000 characters. Information on DBCS fonts can be found in the following technical
references.

DBCS resident fonts are not included in the Card for IPDS and SCS/TNe. DBCS fonts required to print a
job must be downloaded with the job from the host. DBCS fonts that are marked eligible for capture on the
host can be captured to disk or flash in the printer. Once captured, the fonts are treated as resident fonts
and do not need to be downloaded with each job. This reduces network traffic and saves printing time
when this font is requested for use in printing of future jobs. Capturing the fonts to disk is recommended.
Due to the large size of the fonts, only a few fonts can be saved on user flash before the flash becomes full.
See section 3.10.1 on page 49 for information on how to capture fonts.
Print the Menu Settings page (in the printer's Reports menu) to see how much memory is installed in the
printer. If the memory installed is equal to or greater than the required minimum (shown below), select the
following settings to enable DBCS characters to print:
1. IPDS Emulation – Select the Resident emulation. The 3812/3816 emulation does not support
DBCS printing.
2. Host Resolution – Select Auto or the resolution that matches the raster fonts stored on the host. If
you need to use 300 dpi and 240 dpi raster font resources in the same job, select Auto.
DBCS fonts require a large amount of printer memory for storage and printing during an IPDS session.
Depending on the language, one font can require up to 15 MB of printer memory for temporary storage
while printing a job. Because of the additional memory requirements to store and print DBCS fonts,
additional memory is required in the printer. When an IPDS session is started between the host and printer,
the printer reports resident resources and IPDS functions supported. The printer reports that it is capable of
printing DBCS fonts when the printer contains a minimum of 128 MB memory. Attempts to print DBCS
characters to a printer with less than the required memory will usually result in a message on the host
indicating the printer does not support DBCS fonts.
