g - generate font cache
Scaling fonts in the printer´s memory requires a lot of calculation- and additional processing time.
This is sometimes visible, when the data changes from label to label, combined with high speed
printing .
The printers use an internal cache to handle characters which have been printed before, but this
takes effect earliest if a couple of labels had been printed. JScript contains methods to separate font -
and barcode scaling for time critical applications. The font cache preparation command is used to
prescale characters in the font cache.
Prescaling needs additional memory of the printer. This might become critical especially with Apollo
or Hermes printers, depending on the size of the downloaded data. This command is not supported on
A-series and M-series printers.

size =
text size - scalable fonts use either in pt, millimeters, or 100th of an
inch (millimeter or inch depends on the printer´s setup language or on
the "m"- measurement command.)
Bitmap fonts are defined with horizontal and vertical size factor.
effects=
optional parameters, describing special formatting effects for fonts.
Not all effects are available with each font. Please refer to the "text
field definition " commands.
description = defines which character types shall be calculated. All characters
will be calculated as long as they are not limited.Limitations for saving
