Once you've specified:
Display format
Scale factors
Dump data
Block data
Cursor data
Dither data
Minimum bitmap height
Vertical text offset
Spot diameter
you should add this data to the minidriver's data table. In order to do this, choose either the Add Res or the OK pushbuttons.
There are four Graphics Info commands: Resolution, Compression, Color, and RectFill. Now that you've initialized the Resolution component, you should select the Compression option in the Graphics Info menu and enter the appropriate data for your printer.
