The HP Q2344A, 1918 dye-based black print cartridge achieves excellent decap times for intermittent printing conditions, and produces optimal image quality, print speed, and dry time on a wide variety of substrates.HP designed the Q2344A, 1918 dye-based black print cartridge specifically to support intermittent industrial printing on a wide variety of substrates: coated and uncoated papers, labels, and specialty media.This dye-based ink optimally penetrates the surface of the substrate, producing sharp, crisp output without smearing or transfer - ideal for the packaging industry and other markets that need consistently robust results. On coated substrates, such as photo papers, this dye-based ink enhances the glossiness of the medium.Higher decap times reduce nozzle dropouts in production environments with intermittent printing requirements. Unlike some pigmented inks, the dye-based ink in this print cartridge is water-based, not solvent-based, so production facilities do not need additional ventilation, special chemical cleaners, or qualified service technicians who can handle solvents.
