A:Answer Hello, Steve. Thank you for your question! The HP 64 ink cartridges generally last longer than the HP 67 cartridges. The standard HP 64 black cartridge yields up to 200 pages, while the high-yield HP 64XL black cartridge can produce up to 600 pages. In comparison, the standard HP 67 black cartridge yields up to 120 pages, and the high-yield HP 67XL black cartridge yields up to 240 pages. These yields are based on 5% coverage, with full-page photos being 100% coverage. The HP ENVY Inspire 7955e Printer is compatible with HP 64 and 64XL cartridges, but not with HP 67 or 67XL ink cartridges. For longer print life, opt for the HP 64XL cartridges.
