Squares printing on page, odd font issues.
I created and uploaded a pdf of the book (not my frst rodeo here).
I downloaded the pdf that I uploaded. Good. No issues.
Then Lulu created a "Print-Ready File" and I downloaded that. Now there are missing letters, odd spacing, and square boxes in the text. Font was embedded when the file uploaded and I can open and print the file from multiple programs with no issues.
