Can you print postage on an envelop with no plastic in the mailing window?
Do you know of anyone that prints postage directly on envelopes that have a plastic window for the mailing address? We are having issues with the plastic melting in our printer. We would like to be able to print the postage and return address on the envelop and the mailing address will be showing through the plastic window. Or even anyone that prints only postage on an envelop with no plastic in the mailing window and gets a good quality envelope out of the printer. Our printer tends to wrinkle the edge of the envelope.
Laser printers set the toner using heat and that’s why your window is melting or sticking. Inkjet printers don’t use heat, but the ink isn’t as durable. Stamps.com actually has a video covering this very issue, it might answer your question. Also, some laser printer envelope feeders crimp the envelope corner over time, it all just depends on your printer. I hope this helps!
