I'm experiencing issues with an exported PDF from InDesign. More specifically, when I export the InDesign doc to a PDF and try to print, I don't have any issues, nor does anyone else in my office, however some of the people that I'm sending the document to are experiencing trouble printing it. They get to 44% flattened and then the printing process slows down, and then once it reaches 50% they get a pop-up window saying that the document can't print and the whole thing stops. They can print the first page by just selecting that page, however the second page cannot be printed this way. I have re-exported the PDF several times and these folks having the issues have cleared their browser cache, re-downloaded the document, saved it to their desktop before opening, and tried renaming the document as well.
What's going on here, and what can I do or tell them to do to fix this?
Also, updating their Adobe Reader or Adobe Acrobat does not solve the problem.
