I use all the colour combination of HP920XL for printing all forms of documents and they serve me very well

Clean Replacement, Sharp Tones & Colours

the use of these cartridges immediately sent my printer into a printer head and ink system FAILURE which I still have not been able to correct. Will NEVER buy again!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Buying the bundle saves a few pounds over individual cartridges. HP ink quality seems as good as any on the market and cost per page so far seems lower than other brands. These XL cartridges claim 1200 pages black and 700 colour, though that is mixed coloured text, not photos.
