My Son sent me an email with 2 PDF File Attachments , Asking me to Print Off for Him.. 1st PDF File like Soft Butter on Bread, No Problems.. 2nd PDF File , Nope Nada.. I can bring up the pages through the email and look at what is to be Printed Off.. But once I set Printer in motion, iPad Finds Printer, Choose Color or Black & White.. Then Click On Print, Window showing Page to be Printed is (Blank) Page just comes out Blank.. The How & Why of it has me Stumped.. Thoughts, Ideas Appreciated.. Cheers Thanks
