3.2 Minidriver Version Number
The Minor box contains the version number of the minidriver. This value can
be any integer between 0 and 255.
If the driver has already been built and installed with Control Panel,
changing this value and rebuilding the minidriver will cause the Universal
Printer Driver to rebuild the driver's font-summary file. A font-summary
file contains a list of fonts currently available for a particular printer
model either internally or by the use of downloadable fonts and the font
installer. For those printers using a Windows printer driver that can
download soft fonts using a font installer (as with the HP LaserJets and HP
DeskJets), the Universal Printer Driver will build a font-summary file.

The Minor box contains the value 1, specifying that this is the first

forty-first version of the minidriver.
