The HP 301XL Tri-Colour (CH564EE) is a high-yield, original HP ink cartridge that contains dye-based cyan, magenta, and yellow inks. It holds 6 ml of ink and delivers a page yield of around 300 pages (tested using HP’s ISO methodology).The cartridge has 612 nozzles and supports a wide range of drop sizes (from 2.3 picolitres to 8.5 picolitres) depending on the print mode, which helps it balance quality and coverage.  It operates well in typical printer environments, with a working temperature range of 15–32 °C and relative humidity between 20–80%, and can be stored in much more extreme conditions (from –40 °C to 60 °C). The ink cartridge is compatible with multiple HP DeskJet, Envy, and OfficeJet printers. According to HP, about 60% of the cartridge’s plastic is recycled, making it a more environmentally mindful option.
