Don't print them onto vinyl, cut them out of vinyl. They're all single-color or two-color with no gradients, so they're designed to be cut. You can get a cheap little USCutter MH series for under $300, blades from aliexpress for $15, and a few rolls of vinyl and transfer tape from Wensco for about $20/ea. That's well within the price of a good printer, and the results are substantially higher contrast and more durable. (Friends don't let friends pay the Cricut tax. Commercial-grade machines and materials are vastly cheaper in volume.) Your local hackerspace/makerspace likely already has one.
