Standard vs. XL — which should you buy?
HP 934 or 935 cartridges come in standard and XL (high-yield) sizes. Standard cartridges cost less upfront; XL cartridges cost more upfront but typically print two to three times as many pages, so they usually work out cheaper per page if you print regularly. If you print only occasionally, a standard cartridge may suit you better, since ink can degrade before you use up an XL cartridge's larger capacity.
Standard and XL HP 934 or 935 cartridges are physically and electronically interchangeable in printers in this family - you can mix a standard black with an XL color cartridge, or switch sizes the next time you reorder, with no printer settings to change. For the full cost-per-page breakdown and when each size makes the most sense, see our guide on standard vs. XL cartridges.
