Frequently Asked Questions
How does A3 paper printing impact the rated page yield of the 45 cartridge?
The rated yield of 883 pages for the HP 45 (51645AA) black cartridge is calculated using standard A4 pages at 5% coverage under ISO/IEC 24711 testing. Printing full-size A3 technical drawings or CAD diagrams uses twice the printable surface area, effectively reducing the expected page count per cartridge by roughly half.
Can the HP 45 black cartridge print crisp text on heavy paper stocks?
Yes, the HP 45 (51645AA) cartridge contains pigment-based black ink, which binds to paper fibres rather than absorbing deeply. This produces sharp, water-resistant black edges on heavy bond paper, cardboard stock, and matte media up to A3+ size without feathering.
Why is pigment black ink preferred for Deskjet 1280 wide-format prints?
Pigment ink in the HP 45 (51645AA) cartridge provides high optical density and fade resistance compared to dye inks. This makes architectural plans, technical diagrams, and large-format text documents clearly legible and durable over extended storage periods.
