I'm a Help Desk technician and not a user so forgive me but I have a client who gets random issues where she can't print a PDF from Acrobat XI or sometimes from Word 2010. She thinks it started after they installed InDesign.
Has anyone experienced this and can someone shed light on how InDesign might have hooks into Word or Acrobat?
There is absolutely no relationship between what InDesign installs (and uses) and the operation of Microsoft Word and Acrobat. InDesign does not install any system components or share any system components with Word and Acrobat.
Look elsewhere for causes and solutions. In the case of Acrobat, if you have specific issues with printing with specific types of PDF files and/or devices, post your questions on the appropriate Acrobat forum (“Printing and Prepress”).
