I recently upgraded to Yosemite on my iMac and have just discovered a problem with printing from Photoshop and Lightroom...
Printer is a Canon ip5000, and it works ok with adobe reader, open office, safari....
Tried printing today from Photoshop and it took it's usual slow time but put out a complete blank paper, tried with lightroom, same result.
Have checked all the utility stuff, printed tests ok, printed from other applications ok.
Anybody got any clues as to what might be happening...
TIA
Phil
