Dye sublimation will do part of one of your wants. With dye sublimation you can put images on performance fabrics (polyester). I’m not sure exactly what your cloth and vinyl material is, but a lot of vinyl product can’t withstand the high temperatures used in dye sublimation. Dye sub can also be used to decorate lots of other substrates, as well. I am in the process of redesigning my Dye Sub 101 class to make it easier to teach. It currently take both my wife and I, and her schedule is massively booked these days. The printer for dye sublimation uses ink jet technology, it is not a laser printer, and it is only for printing dye sub transfers.
For stickers, I assume you want to learn to use the vinyl cutter. I don’t currently see any classes on the calendar, but there are usually a couple a month. Calling @talkers, are you planning a Vinyl Cutter and Button class soon?
Laser printers use dry toner, not ink, and the only one we have at the Makerspace is the copier outside the Interactive classroom. I’m not sure how adjustable the settings are on it. What kinds of paper are you trying to print on that are causing you problems?
