The Canon PG-545 black ink cartridge works with a wide range of the popular PIXMA printers and is intended for everyday printing tasks. The sort of thing this cartridge is perfect for is printing boarding passes, tickets or any text document. Despite only containing 8ml of black pigment ink the PG-545 is capable of producing an astonishing 180 pages of A4. This total was reached under laboratory conditions but an average home printer can expect to achieve similar results provided the print head isn’t clogged or dirty.
