HP Officejet Pro 7740 - A3 not printing in colour

[Roche57]

I see this subject has been covered a fair bit. I found today that I now cannot print A3 colour from Poweroint and PDF, the printer is fine at A4 and used to be fine at A3. Firstly checked all the settings and ink (all gen HP) - All OK.

Unistalled the HP driver and Smart suite at root, then reinstalled from HP Smart from HP site, guess what no change,

Now the interesting thing is that if I select the "No border" option, it prints in colour on A3, uncheck the box I get greyscale.

Surely this has to be a driver glitch?

Thanks in advance for your help.
