Thanks you, EFF for giving us useful information about how the
government and colluding corporations wish to track us.

How is a printer able to print those dots on so many pages? At some
point, this special yellow ink must become depleted, right?Or does
it use the regular ink which is provided by the printer's
cartridge? If this is the case, isn't a possible defense to just
not buy new color cartridges? At least for me, I have to print
colored documents at most every 3 months. Unfortunately the color
cartridges dries out after about 6 months which means I would have
to pay $20 to print less then 10 pages. Thus, I only buy the black
ones and when I have to print something in color, I just put it on
a USB stick and print it at work (I am allowed to do that in
moderate amounts) or go to a shop with printing services and pay $1
for those documents.Since my color cartridges are almost two years
old (and still full according to my printer), though I cannot print
a single page, am I still "affected" by those tracking dots?

The printer uses the yellow supply from your ink or toner. There
have been reports of some printers refusing to print monochrome
when the yellow is empty, presumably for this reason.Anecdotally,
my yellow always runs out earlier than my C and M cartridges on
my home printer, and I mostly print monochrome (these days it's
really just character sheets and other stuff for tabletop RPGs
that I run)
