The plotter doesn't need a specific driver - it doesn't even have one.
In
Windows it uses any old printer driver just to open the printer port,
then
sends commands to the plotter through the printer driver.
Should it not be possible to do this with Wine? Possibly not with CUPS though...
Well that should work with cups too, you need to configure a printer with model "RAW".
It doen't - I get a an error saying "Call to StartDocPrinter failed"
