I have vertical lines spaced at 1/2 inch in my printed pictures and would like to get rid of them.
It happens with Photoshop CS-6 but not with Microsoft Photo Editor.
I'm using a HP Officejet 6500A Plus and the color printing is fine. John
Additional info: I am using Windows 7 on a Dell. Service pack 1, 32 bit system.
It happens with pdf files, jpeg, and psd. I am managing colors with the printer. I am using best quality printing. I have tried ColorSmart and Adobe settings for RGB on the printer dialog page. I have tried telling the printer that I am using HP premium plus, plain paper and Other photo papers (My paper is actually Staples high gloss photo supreme).
What is remarkable to me is that I get high quality prints with the same printer, same paper, same settings using Microsoft Photo Editor - no vertical lines at all. However MPE is not very versatile, and the pdf I am currently trying to print will not load onto MPE. John
