I'm curious if you found a printer that will feed A-2 envelopes. We print return addresses on the back flap and can't find one to replace the last one we had that worked.
Our Pro-100 printers will not feed A2 envelopes no matter how many times we try. Using custom settings/envelope setting, it doesn't matter. It pulls in the flap and envelope body separately in such a way as it destroys it.
