I print with an Epson 3880 using LR. In the past, it acted very erratically (not printing the size photo I entered in LR) and discovered the problem was that I was using a 3 foot USB extension connected to my 10 foot USB A to B cord (necessary because of distance from computer to printer). When I got rid of the extension, the problem went away (Epson states that 10 feet is the maximum cord length to use). After two years of trouble free printing, the problem has started again, although with less frequency. I am wondering if I used an active USB cord if that would help, but unfortunately can't find a 10 foot active USB A to B cord. Anybody know where to find one, or even if they make them? I would prefer not to print using ethernet...
