Honestly you could probably get a decent toner based printer and just buy label sheets from Online Labels.com. We still buy materials from them sometimes to run on our digital presses because you can buy precut sheets of labels by the sheet, which can be a lot easier and more cost effective for short runs of custom jobs.
Inkjet won't give you the durability you need for outdoor.
Any brands/model numbers of "a decent toner based printer" is all I need. Way too many to sift through the fine print to find out which ones will work with stickers/decals. Thought my B&W laser printer (Brother HL-L6200DW) would, but turns out it don't like stickers, and will jam at any opportunity. If I cough up the money for a color laser printer, it will be just for stickers, so it has to work.
Already know of where to buy label sheets (vinyl, mylar, and polyester), ink, automatic sticker cutters, etc. Only thing holding me back is the printer.
