AutoCAD 2010 :: Publishing With Office Wide Page Setup Overrides?

Without our office, we set up Sheet Sets for every set of drawings we produce, and we setup Page Setup Overrides specific to those drawings from which we can print.  We may setup one for printing fullsize PDFs, another for in-house half-size plots, and another for 11x17 printing.  The Overrides are saved on our office network.

We've been having an issue where the plotter(s) in the various Overrides won't work initially when someone other than the creator is printing.  That person will have to open up the 'Manage Page Setup Overrides' tab, select 'Modify' for the Override they wish to change, and select the plotter to use in that Override (the plotter always defaults to 'None').  They can publish from that particular drawing set just fine until someone else in the office needs to print using an Override, in which case they go through the same procedure listed above.

We're using network printers only, and we've verified that the printer names, ports, etc. are all the same between the various computers, so different naming or port selection doesn't seem to be an issue.
