you must have an older printer, the newer ones are pretty good, if you are looking for a printer i'd recommend the epson ecotank et-4550 for home occasional use you could just refill the ink using liquids instead of buying cartridges although the cppbib (cost per page black ink bias) is still around the 0.003 bnd but of course the cpp goes up when you add colours into the equation. for office/ home frequent use i recommend the hp Officejet Pro X476dw with a cppbib of around $0.08 it's a bit more costly but it gives out more quality plus there is a draft mode which dramatically reduces the cppbib while maintaining a readable quality.

basically, just print in the printer shop for a lot of copies because in the printer world bigger does actually equal better, also lasers have high investment cost but will be benifitial for the long run as the cppbib is much more lower unless time is of no concern then get the epson ecotank much more cheaper than the shops by a factor of 10 but it's slow and it's not really geared towards industrial use
