If it's already printable, I also think you should do a small print run and sell them at conventions! Those must be starting up again soon in most places, right? See how many you can get within a budget you can afford, and see how many you can shift.
Christmas markets will also be a thing in four months or so, and there are the occasional book markets and such in most cities. Both of those are good options for selling a physical comic.
You could have them uploaded on WEBTOON/Tapas at the same time - people tend to buy physical comics because they like that format, and they like holding the physical object, so you could double-dip by stacking the panels for a vertical web release, and selling the original format in a physical-only copy.
