Max Font Buffer
The maximum amount of DRAM allocated for downloading fonts (TrueType,
Scalable, or Bitmap). DRAM allocation will not take effect unless you save it in
a configuration and the printer is powered up with that configuration.
The range is 100 to 1800 Kbytes, and the factory default is 1100 Kbytes.
Max Cache Memory
The Maximum Cache Memory option specifies the size of the memory block
that can be allocated to the font cache. The font cache stores bitmaps that are
created on demand from the font outlines stored on the printer flash. The
cache allows the printer to print scalable fonts at optimum speed. Memory
block allocation will not take effect unless you save it in a configuration and
the printer is powered up with that configuration.
To calculate the memory requirement, use this equation:
(HS x VS x Average Height x Average Width x NumOf Char) / 8
Where: HS = Horizontal resolution
VS = Vertical resolution
Average Height = Average character height (inches)
Average Width = Average character width (inches
NumOfChar = Number of Characters to be cached
The allowable range is 50 KBytes through 2000 KBytes in 50-KByte
increments.
The factory default is 1700 KB.
NOTE: For most applications, the default settings for font memory are
acceptable. Therefore, do not change the defaults unless your
application requires an uncommon memory configuration.
Max Cached Char
The Maximum Cached Characters option specifies the size of the largest
character that can be stored in the font cache. This will not take effect unless
you save it in a configuration and the printer is powered up with that
configuration.To calculate the memory requirement, use this equation:
(HS x VS x Average Height x Average Width) / 8
Where: HS = Horizontal resolution
VS = Vertical resolution
Average Height = Average character height (inches)
Average Width = Average character width (inches
NumOfChar = Number of Characters to be cached
