Photoshop Printing not true colour

[Melanie26689997w6su]

What are the best settings for printing from Photoshop to a Canon 100 pro series, to get bright colours and true black. 
All of a sudden my prints are coming out dull and not bright coloured. 
All cartridges are full - printer nozzles heads have been cleaned. 
Print test shows true black and bright colours.

Check if Photoshop is managing colors instead of the printer and make sure you're using the correct ICC profile for your paper. Also, try soft proofing in Photoshop to see if colors look different before printing. Double-check your printer settings for media type and quality. If nothing works, reinstall the printer driver!
