Windows printer settings have switched to Greyscale or Monochrome choices only

[Catspaw666]

I have a 2600 all in one printer. I have lost the ability to print in colour, the settings 'printer preferences' tab now only has a choice between greyscale or monochrome...but a test page printed the colour portion as normal...I notice that the driver in the printer properties is 'Microsoft IPP Class Driver'...could this be the 'problem'? How do I get back the print in colour choice? Have I deleted the HP Driver somehow?!
