I had to reinstall the drivers for my 4250 on Windows 7 (64-bit) but none of the Universal Printing drivers (PCL6, PCL5 or PS, all 5.8.0.17508) can print above 600 dpi now. The "Full service" download does not seem to be available any more.
I have no idea what the old drivers stopped working. Any idea where I can get an older driver or some other way to get my hi-res printer back? (I would prefer to go through HP, since the third-part drivers have so much spyware, etc.)
