its a security feature.

every time you print a document there are a series of tiny yellow dots hidden on every page that relates to the serial number of your printer.
this allows forensics to link a printed document to a specific printer quite easyly.

blame the cia/fbi/nsa types for this!

This is only for laser printers (currently) - and there's no legal obligation for the manufacturer to include them.

It was supposedly introduced to stop counterfeiters printing/copying currency as they thought the printers/copies were so good that it would become a concern. Personally I'm lucky if I can get the colour printers at the office to output straight text or properly overlaid/aligned colours.

Here's a list of those that do/don't include them, so you can purchase bases on that information. But if you're really paranoid then just print on an officer printer.

So what happens when you printin B&W or only have a monochrome printer?

dont know but im 100% certain about the yellow dot code being on colour printers.
