      @vkc Somewhat ironically, the old dot matrix should be free of tracking dots.

                        Sadly, when I was starting my new bank account last year, they just printed two copies of the paperwork on a laser, and why wouldn't they, it's fast as heck.

                          Or just print out random yellow dots on the pages first, then feed it back in again for the print run.

                            @vkc @Kiloku As a kid, a friend and I ran a small neighborhood newspaper. We talked businesses into advertising in it, and distributed it in a maybe 10 block area because many people needed birdcage liner, and also because who didn't want to read a review of a TV show by a kid?

                            We talked the bowling alley into letting us use their mimeograph machine in exchange for an ad placement.

                            Mmmm. Mmmmimeograph smell.

                                @vkc Thank you. The Wikipedia article helpfully refers to software to help remove the pattern before publishing scans and thwart recognition of your printers pattern by adding a mask before printing https://github.com/dfd-tud/deda

                                  But I believe the impacts could be analysed and compared instead.

                                  Buy a spare print head and bury it in the forrest, when not printing secret stuff.

                                  Keep lots of example of printing with your normal print head.

                                    @ozzelot @vkc used to be (at least in Italy) that two copies that were not the result of a single unique action weren't legally considered actual copies, I believe.

                                    Plus, yeah, when printing hundreds of invoices in the early 2000s it was probably faster and cheaper (I remember pre-printed forms of continuous paper that would make 5 copies in one go).

                                      Shipping companies still use them but it is becoming increasingly rare even amongst them (CMR form if memory serves me right)

                                      Fun fact: I used to work at a call center supporting software that allowed printing those forms. I can't tell you how many little tips for resolving printer issues we had - but rarely if ever had genuine unsolvable defects. And if something broke, replace the part *maybe* recalibrate and off you go

                                        @vkc Related: a lot of things labelled as "fax machine" can actually also function as stand-alone USB printers. And "fax machines" are often free on classifieds, and use cheap generic cartridges/toners, and (aside from stuff like doorbell cameras) that means there's basically no paper or money trail from the original purchaser to you at all.

                                        It's not a bad way to get hold of a more or less anonymous printer.

                                          Shipping companies still use them but it is becoming increasingly rare even amongst them (CMR form if memory serves me right)

                                          Fun fact: I used to work at a call center supporting software that allowed printing those forms. I can't tell you how many little tips for resolving printer issues we had - but rarely if ever had genuine unsolvable defects. And if something broke, replace the part *maybe* recalibrate and off you go

                                          @Aprazeth @ozzelot @vkc good old 120 columns Brother printers... They'd shake the table like a washing machine
