HP 45 Black Ink Cartridge

The HP 45 black original ink cartridge is an OEM supply for HP DeskJet printers including models 712, 720, 722, 820, 830, 832, 850, 855, 870, 880 and 882. It uses thermal print technology to deliver black output for everyday document printing. Buyers who need colour printing or high-yield capacity should look elsewhere.

Installation and common issues

The cartridge measures 6.200 by 4.560 by 1.000 units and slots into the designated carriage on compatible DeskJet models. Installation typically requires opening the printer cover, removing the old unit and pressing the new cartridge until it clicks. Misalignment or clogged nozzles may occur if the printer sits unused for long periods.

Page yield and limits

Rated at approximately 930 pages, this cartridge suits light home or small-office workloads such as letters, invoices and schoolwork. Heavy daily printing will exhaust the supply quickly and increase per-page cost. Users with high-volume needs must plan for frequent replacements.
