There is no use arguing with the excuses MS provides, they "know best" <sigh>. While it is true that many people use Office in the business Office, in my experience, most/much of the time they use a single printer so saving the printer info in the doc would
be a time saving setting. For times you are printing from other machines/locations, it would be easy enough to create a process that would notify the user of the "missing" printer.
Yes, I agree, Word has "never" (I started with Word 4.0) kept printer configuration information in the document. I think it is unfortunate design choice that MS never fixed.
The only work around I know of is to record a macro while you make the printer setting selections. The at least you don't have to manually reapply all of the settings, you can just run the macro.
