Activating Font Memory Options
After selecting any of the “Font Memory” options, perform the following steps
to activate the new value:
1. Save your configuration changes. See the Config. Control menu option
“Save Configuration” on page 57.
2. Change the power-up configuration to match the configuration you just
saved. See the Config. Control menu option “Power-Up Config.” on page
66.
3. Turn the printer power off and then on again.
Max Char Memory
The Maximum Character Memory option specifies the size of the largest
character that can be printed. To calculate the memory requirement, use this
equation:
For example, if an application requires a character that is 4 inches high by 2
inches wide, calculate the Maximum Character Memory value as follows:
Therefore, select a value that is equal to or greater than 41,209. The closest
available value is 50 KBytes.
The allowable range is 50 KBytes through 900 KBytes, in 50 - KByte
increments. The default value for this parameter is 300 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.
To calculate the memory requirement, use this equation:
The allowable range is 50 KBytes through 900 KBytes, in 50-KByte
increments. The default value for this parameter is 200 KBytes.
