HP 975A Magenta Ink Cartridge (L0R91AA) — Genuine HP Ink for PageWide Pro

Looking to buy an HP 975A Magenta Ink Cartridge in Australia? The HP 975A Magenta (part number L0R91AA) is a genuine HP ink cartridge for the HP PageWide Pro 400 and 500 series, delivering up to 3,000 pages of rich, vibrant colour output. Whether you run an HP PageWide Pro 452dn, 477dw, 577dw, or 577z, the L0R91AA is the correct genuine HP magenta ink cartridge for your machine. Need even higher yield? The HP 975X Magenta (L0S03AA) delivers up to 5,000 pages.

What the HP 975A Magenta L0R91AA does in your printer

The HP 975A Magenta Ink Cartridge L0R91AA is the magenta component of the HP 975A CMYK ink set for the PageWide Pro, working alongside the HP 975A Black (L0R97AA), HP 975A Cyan (L0R88AA), and HP 975A Yellow (L0R94AA) to produce full-spectrum colour output at speed. Magenta handles the warm side of the colour spectrum — reds, pinks, and the vivid secondary tones that keep brand colours accurate and customer-facing documents looking sharp. Without a genuine HP 975A Magenta L0R91AA, warm-tone accuracy suffers across every colour document your PageWide Pro produces.

Why genuine HP 975A ink matters

Genuine HP 975A cartridges like the L0R91AA are engineered specifically for HP PageWide Pro printhead technology. Third-party and compatible alternatives for the PageWide Pro frequently cause printhead damage, inconsistent colour output, HP firmware rejection, and voided printer warranties. The genuine HP 975A Magenta L0R91AA is tested and certified to deliver consistent, vivid colour in your PageWide Pro from the first print to the final page of its 3,000-page yield.
