Envelopes feeding through but not printing.
I'm trying to print envelopes from Contacts. It looks like the information is being sent to the printer, but then the envelopes just feed through without anything printing on them. I've just updated everything (I'm on Yosemite 10.10.2) and I've been able to do this in the past (before Yosemite). What can I try? It's an HP Officejet 6700 and anything else I try to print comes out just fine.
