I have an Epsom EP-960 and when I try to print A3 size from Lightroom I am getting faint lines at 25mm spacing across the picture, I have printed the same picture from Epsom Easy photo print software and I get no problems, What is wrong in the LR software?
Cheers in anticipation
By any chance do you have High Speed turned on in the printer dialog? Try turning it off.
Yes it was turned on I have now turned it of and will see what happens the next time I print an A3 and will let you know.
