Most of The labels I print come directly from eBay. Sometimes I will have a PDF or JPG of a label to print. Those I click CTL-P and select the printer.
I did play with CUPS a ton, adding custom files, all that. Nothing worked. That’s why I bought 2 other no name label printers to see if those would work. But same issue.
I ended up buying a rollo printer, hopefully hay just works.
Thank you for your advice.
