We include Left, Center, and Right side feed options in the software. When you think you have it right, cut a sheet of plain paper the exact size of the envelope and try printing. In that case, set your printer to Landscape and rotate the envelope accordingly. We show you pictures in the feed setup options. Finally, don't stuff a bunch of envelopes into your feeder and walk away.
Printers have a habit of jamming.
Feed each one at a time. As one is pulled in, slowly insert the next envelope. If your printer hangs half way through printing, you do not have to start over. We have included the ability for you to select an individual addresse or a new start point for resuming printing.
