More information will be needed – which version of PS and OS, is your monitor calibrated, what do you mean by discoloured, are you printing from RGB color mode and using your desk-top printer's software to convert to CMYK / CMYK+, and so on?
I'm using PS creative cloud with LR. I just updated so its the latest version of photoshop. I've been using LR for a while now and just started editing on PS but when I save my photos and print them the color is off. I've never had this issue with LR. My photos look great on my monitor but when I go to upload and print them look awful.
No my monitor is not calibrated but I've never had this issue with LR, it's only photoshop. I have gone into the Edit and convert to profile where the sRGB format was different but it's still not printing like it would from LR. I usually go to a local printer or send my prints off to Millers.
