In order to publish to a printer you need to have a valid page setup for that printer to use. In any drawing use the page setup manager to create a new page setup. It will give you the plot dialog so you can select the printer and all other settings you need. Save this drawing and in the publish dialog box highlight all your sheets then in the page setup field pick on the top page setup and a down arrow will appear. Pick that and select import then find the drawing you just saved and get the page setup you created.
