Our 4015's have envelope feeders and worked fine with XP but not with W7. The envelope feeder is configured for envelopes / #10 but printer insists on inserting envelopes into Tray 1 which is configured for letter / letterhead.
We have tried all the drivers listed on HP's driver download page but cannot get it to print from the envelope feeder. A few of the drivers think the 4015 is a color printer (cm2320) and prompts for colored envelopes in tray 1.
Is anyone else having this issue?
