First, could we ask for a little more information? If they are exporting into a PDF to print what paper size are they selecting before downloading it?
Next, are they using the "Print Screen" option on their computers or are they downloading it first and then printing the save file.
Are you seeing this issue on all campaigns or just some?
I have a similar situation. When printing a campaign from your download/print option page, the text at the page breaks often cut off the bottom of the page and top of the following page. Doesn't matter what size I set it for in the download area, it still cuts off text on either side of the line.
I too am having this issue. I download from the campaign and try to play around with the sizing, but it doesn't have clean cutoffs and sometimes the line that is cut off is not visible when I go to print.
