This took me about 5 hours to figure out, because Repairshopr doesn't really have any support for printers.

For whatever reason, the receipts that were coming out of my printer, were printing faded, small, and only filling up about 50% of the receipt width. I tried everything from reinstalling the printer, reinstalling through Google Cloud Print, Trying different drivers, messing with CUPS settings, calling support, pulling out my hair, throwing the printer across the room, and setting it on fire. None of these things helped.

I thought it had something to do with my disclaimers, and sure enough it did. But even though I removed ALL disclaimers from PDF/Email Templates>Receipt Configuration>Advanced, but it still didn't fix it. But what finally DID fix it, was a hunch. So I thought there may be some kind of weird conflict, and I went to PDF/Email Templates>Invoice Template and then I chose the "Receipt Disclaimer" tab at the top. I then went in there and removed all of my disclaimer and it fixed the receipt issue.

I hope this helps someone. Peas.......
