I would like to offer a client 4 color printing on 9 x 12 booklet envelopes that I intend on printing on my Versant 80. The quantities may go up into the several thousands. Question is, can anyone relate the best way to feed these envelopes through the printer? I do have two high capacity drawers that would be preferred for use, but don't know if others have tried and resorted to using the bypass tray. I know I could trial and error this, but experiences are always welcome here. Thank you!
