90s digital typewriters can store a page in memory and print it in bulk. Early teletype systems could possibly be used as well, taking serial ascii input
So if you registered your printer with the manufacturer and/or use their printing app or software this makes it easy to track you down but for the most part I suspect it's for when they know it was you & just have to prove it, like if they have a warrent to collect any printers on your property, in which case a second hand printer doesn't help if you still have it or there is footage of you throwing it away.
But if you go to a printers or the library to print and pay cash, simply wait 30-90 days before using your print and the CCTV will be deleted but then you run the risk of employees seeing what you printed and remembering.
I thought everybody already knew about printers having unique markers on everything they print that are used for tracking purposes. .
Yeah, obviously if you are going to do IRL activism like posting up or handing out antisemitic/racist flyers and the like, you better use a really old printer from a garage sale before you go fuckin around, or at least make sure the state you live in won’t give you a littering charge with a hate crime multiplier on top of it. I’m pretty sure the tracking shit dates back to the early 2000’s, so you’d wanna find a printer from the 1990’s to be safe.
