photo printer colours

[squelly]

my hp photosmart 7760 printer as started printing photos with a blue tint all over ,making the photos darker all over .could it be cheap inks.

Always use the recommended cartridges and NOT own brand/reused.

Sounds like a dodgy cartridge to me, or the coloured inks are running out. Try a proper cartridge and see what happens.

Or do a cartridge head clean.
