Banding in prints. only when printing from photoshop

[adamj77969994]

Hello. I've been having issues with print quality when printing from Photoshop.  Ive been getting dark horizontal lines going through my prints. This is not happening when i print from any other application. I have set my prints to CYMK and have put that Photoshop manages the colors. Photoshop is fully undated. I might be missing something quite simple. Any help with this would be much appreciated, before I realized it was just a Photoshop issue I spent a long time cleaning my printer, doing nossle checks and trying different inks. so i cant wait to find a resolution for it.

Thanks

what printer? What platform? What OS? What version of driver? Why are you using CMYK?

I'm guessing that your issue is because your file is set to CMYK.  Although your inkjet printer might use CMYK inks, your file should be sent as RGB. I suggest going back to your original RGB, before the conversion to CMYK, and resending.

Let us know how it goes

I have had exactly the same problem, printing on an Epson Workforce printer, printing from Windows (latest version), using RGB formatting of the colours.

I have printed hundreds of test pages, done the cleanings and nozzle cleanings etc, letting both the printer and photoshop manage the colours.. and lots of other things. Suddenly realized it printed fine from the standard Windows photo viewer....

I have just solved it! Adjusted the quality in printer settings from Standard to High - and the bands disappeared.
