Looking for something that is not a relic of the past for which there are no more cartridges available... Ideally a thermal printer would be great but an A4 thermal printer is a rarity on its own :D

I have a couple of old Lenovo laptop that use W98 and XP; a Tandy 100 and a couple of old pc running CPM and Dos5/6. I am looking for something that I can hook up to the parallel printer port of each machine and just print, so it should be as compatible as possible with whatever was most common at each point in time for these machines.

For XP and 98 maytbe I can use CUPS as these machines have a network interface, but anything else just use a parallel port so do not have much alternatives sadly.
