The newest version of Photoshop doesen't print the Labels. Often, printing work previews for verification purposes, I check "Label" option to print the filename on the top of the page. It doesn't work properly.
I am also having this issue, Had to install on new computer and since then having this issue. I spent all day Friday on the phone with Adobe and my RIP people of course they were both blaming each other. at least it is still printing but writing all the info is getting old and time consuming. The Photoshop Expert told me friday that i need to put my Channel information into layers and print it that way. I could not get him to understand that Photoshop does not print layers it only prints channels???
