1 - buy one of those refillable ink tank printers that are now actually common and not expensive;
2 - buy ink bottles at aliexpress for $10 4x200ml ink or around that;
3 - years of ink for a few bucks.
If you have a cartridge printer, search on aliexpress for refillable cartridges for your printer and do step 2 anyway (you can usually refill those easily with a seringe).
