I am using a Raspberry Pi with CUPS and a USB to LPT adapter to enable one of my customers to still print on an old HP DesignJet.

HP dropped support for this printer with Windows 7. Of course the generic HP PS driver with Windows 10 works - but only via CUPS not directly from Windows. Windows claims that the printer is not compatible.

What's wrong with this world?
