are the dots always in the same locations? If so just take an empty document, print it out on the same pieces of paper through 4-5 different devices until its just a meaningless clusterfuck of yellow dots, then print your document. Even if they could somehow decode individual serial numbers it seems like that would give a decent defense... not that any government agency tracking these dots would give a flying fuck about your rights.
The thing that annoys me about this is it seems to imply these printers were designed to print their serial numbers with a finer precision than the document printing capabilities you paid for!
