Canon imagePROGRAF GP-300 Ink Cartridges
Shop ink cartridges for your Canon imagePROGRAF GP-300, which uses the Canon PFI-120 ink cartridges series. The Canon imagePROGRAF GP-300 is a 24-inch large-format printer designed for high-impact posters and graphics using specialised fluorescent pink ink. Ink Depot has been supplying reliable consumables for this printer since Jan 2024. Upgrading from standard 130ml PFI-120 cartridges to high-capacity 300ml PFI-320 cartridges significantly reduces running costs during heavy print runs. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected Output and Ink Capacity
Large-format graphic printing yields depend heavily on coverage, image density, and ink consumption per square metre. Canon wide-format pigment inks adhere to ISO/IEC 24711 standards for yields, though high-density poster prints consume ink at varying rates across individual colour channels.
Selecting Ink Capacities and Delivery
If you produce high-density graphics or volume poster prints, upgrading to 300ml PFI-320 cartridges offers lower cost per millilitre, while low-volume jobs run efficiently on 130ml PFI-120 cartridges. Standard and high-capacity cartridges can be mixed within the same printer based on individual colour usage. Stock up on genuine Canon ink cartridges to maintain peak printhead performance.

Expert Buying Tip
You can freely mix 130ml PFI-120 and 300ml PFI-320 cartridges across different colour slots simultaneously, allowing you to buy high-capacity cartridges for high-use colours like Matte Black or Cyan while keeping standard sizes for low-depletion colours like Fluoro Pink.
Frequently Asked Questions
Can I install a 300ml PFI-320 cartridge alongside a 130ml PFI-120 cartridge in the imagePROGRAF GP-300?
Yes, the GP-300 supports mixing 130ml (PFI-120) and 300ml (PFI-320) cartridges across any slot. The physical outer cartridge dimensions that interface with the printer dock are identical, meaning high-volume colours can use 300ml cartridges while low-use colours remain on 130ml sizes.
Why does the imagePROGRAF GP-300 require specialised PFI-120FP and PFI-320FP Fluoro Pink cartridges?
The GP-300 utilizes Canon radiant infusion technology, blending fluorescent pink ink with standard pigment colours to expand the colour gamut for neon posters and eye-catching point-of-sale graphics. Standard magenta cartridges cannot replicate these vivid tones.
Can I replace an individual PFI-120 or PFI-320 ink cartridge while a print job is in progress?
Yes, the imagePROGRAF GP-300 features a sub-ink reservoir system that retains a small ink reserve. This allows you to hot-swap depleted cartridges mid-print without interrupting the print job or wasting media.
