Print to PDF only works for some users

Hi All, thanks for the add.

I've created a very simple macro that scrolls through a couple hundred clients, creates an invoice for each, and prints to pdf. It works fine for me - anyone can open the PDFs. However, when the user runs the macro, the resulting PDFs cannot be opened. Same file, name, directory, everything. You get an error message : "Adobe Acrobat Reader could not open 'xxx.pdf' because it is either not a supported file type or because the file has been damaged". We're both on Office 365, but we're both remote and have different network connectivity.

Sub Print_to_PDF()

CurPDF = Range("Curr_PDF_Name").Value
Sheets("Data").Select
ActiveWindow.ActiveSheet.PrintOut Copies:=1, Collate:=True, _
IgnorePrintAreas:=False, Printtofile:=True, PrtoFileName:=CurPDF
Sheets("Main").Select

End Sub

Has anyone seen this before? My Help Desk is not Helping.
