I faced a problem. There is a mxd which saved from one machine and then open the saved mxd file, the printer setting will reset to default. Any setting can prevent this , thanks
You may want to take a look at this knowledge base article 29238 - Set up ArcMap page and printer settings
If ArcMap cannot find the same printer, for example, if someone else who doesn't have access to the printer, or if the printer is replaced, ArcMap turns off the 'Use Printer Paper Settings' option and open the map document, but does not change the actual map page size itself.
Hope this helps.
(BTW - although GeoNet names can be set to almost anything, word to the wise, a name like "test test" may not always get any response from the forum, for pretty obvious reasons. I had even ignored it earlier this morning....but to each is own....)
