Printers using the foo2zjs driver (in ports/print/foo2zjs) need to attach as ugen so that a firmware file can be downloaded to them with a command such as 'cat firmware.dl > /dev/ugen0.01".
I got a HP LaserJet 1020 which needs this driver, and currently attaches as ulpt(4) which doesn't work. It is possible to make it appear as ugen(4) by disabling ulpt(4) but I'd rather just have the kernel do the right thing by default. Currently this only adds a quirk for my printer. If this diff goes in I'll later add more printers listed at http://www.openprinting.org/driver/foo2zjs/ once I've obtained their device IDs. Is this fine?
