Actually it is, sort of.
You cannot use it across multiple drawings, but within a singe drawing with multiple layouts, it can be done, however you cannot just select the publish command and get it to work, you have to have all the layouts selected first, then start the publish command.
Select all the layout tabs (control+click, shift+click, or select all layouts on the layout tab right click menu), then right click your tab agian and select publish. you should be able to see and check the "plotter named in page setup" and send them all to a plotter instead of a dwf file.
Good luck with it.
