Q: buying new ink is much expensive so i kinda refill the old one to use in my printer.will this cause damage to the printer?
A: IF (that is a BIG if) the INK is absolutely correct for the printer AND the refill is done absolutely right AND the ink does not have the print head in the same cartridge You should be OK IF ANY ONE of those is NOT the case, you can cause untold problems. Inks can be too thick or too thin. The refill might not be fully sealed after, causing leake If the cartridge ncludes the head, these have a finite life anyway
