When you saye a you have set all the parameters, does that include the cell size in the print module? Are you printing on 5 x 7 paper? And, if you are, have you set that paper size in the page setup?
I am having the same problem. The intent is for 4x6, the cell sets parameters less than that- no adjustments that I can see can be made. This is utterly frustrating. I've NEVER had a problem printing in any other program before- same computers, same cameras! Please help. Thank you.
What version of LR? What operating system, Windows or Mac. Are you trying to print on a 4x6 sheet or something larger? If larger, what size? Can you post a screen shot of your Layout panel as seen here. This is a set up in LR CC on a Mac for printing on a 4x6 sheet with the minimum borders (Not borderless) allowed by the printer. Obviously the actual cell size has to be smaller than 4x6.
FYI, on future questions, you should start your own post; not piggy back on someone else's post. You say it is the same problem, but it may not be. Discussing 2 questions on the same post becomes confusing.
