Pro Tip for HP 27 and 28 Ink Buyers
The 28 (C8728AA) tri-colour cartridge features an integrated printhead built directly into the housing. If one colour runs dry, the entire cartridge must be replaced, so printing heavily in a single shade will deplete the unit faster than balanced document printing.
Frequently Asked Questions
Do the HP DeskJet 3744 and DeskJet 3745 take the same ink cartridges?
Yes, both the DeskJet 3744 and DeskJet 3745 use the exact same HP 27 (C8727AA) black and HP 28 (C8728AA) tri-colour ink cartridges, making replacements completely interchangeable between both models.
Can the printer operate with only a black 27 cartridge installed?
Most legacy DeskJet printers in this series allow single-cartridge printing mode if the colour cartridge is depleted or missing, allowing you to complete monochrome text jobs without interruption.
What happens if a tri-colour 28 cartridge runs out of cyan, magenta, or yellow early?
Because cyan, magenta, and yellow share a single physical reservoir inside the 28 (C8728AA) cartridge, running out of any single colour requires replacing the cartridge to restore accurate colour mixing.
How should I store backup HP 27 and 28 cartridges to prevent drying out?
Keep replacement cartridges sealed in their protective foil wrapping at room temperature until ready to install. Unsealing protective tape prematurely exposes printhead nozzles to air, increasing the risk of dried ink nozzles.
