Print ready file look correct - does not print correctly
I tried to upload a doc file and Lulu's "print ready file" always added or subtracted blank pages no matter what I did to try to fix it. Then I uploaded a pdf file of my work and the "print ready file" from Lulu looks fine. However, the printed proof copy I got had every other page blank.
I have looked for an answer to solving this problem in vain. The first time I had this issue it was finally corrected by someone in the Lulu staff, but I have been having a conversation with a staff member about the same problem again and she just doesn't seem to comprehend it. She says that if the print ready file looks right then that is the way it will print. It does NOT print that way.
I'm at a loss.
