You could have just shown a picture of a modern printer with the same title.
Not enough people still printing these days to be worth the effort of an opensource printer. But in general, yes. Closed source products are always a ticking timebomb.
Some years ago I heard about this German guy that found a mind boggling bug in Xerox scanners and the whole story how they tried to play it down is really insane. So definitely worth watching, unfort only with German audio: https://youtu.be/7FeqF1-Z1g0
He’s written up his findings in English, for anyone who prefers English over German or text over video.
But basically the JBIG2 image compression algorithm used in those scanners looked for certain repeating patterns, and incorrectly compressed certain portions of the image into “close enough” blocks of pixels. Unfortunately, that meant that scanned number data wasn’t guaranteed to be accurate, even when the decoded output clearly looked like a number with no distortion or noise.
It’s worth the full read.
You left out what I feel is the best part: even in the “uncompressed” mode, even when that was disabled, it was still happening sometimes.
I remember that video! For sure worth a watch

I don’t think we’ll have open source 2d printers. Not the way they’re built now, anyway.
On first glance, it might look like 2d is an easier problem than 3d. However, laying down plastic filament doesn’t need the same precision level as 2d ink/toner printing. Even 300dpi is far more precise than any 3d printer does, and that’s not particularly impressive for a modern 2d printer.
That’s not even getting into mixing and aligning color cartridges.
The industry also has a lot of patents around it. So there’s that whole mess to deal with.
Framework looked at making their own 2d printer, and they noped right out.
Would you accept a printer that works like a typewriter with arms that strike the page to lay down text? That might work. They’re mechanically quite complex, though. There’s lots of OK designs that tend to jam up.
Yeah inkjet printers will probably never be opensource, due to the fact that the tiny nozzles are impossible to produce without owning a semiconductor fab that can build stuff in the mems realm.
Laser printers could be the way to go, they sound more complicated, but all the components needed for them are getting cheaper. A laser is focusable to a tiny spot, meaning one can use non mems elements. Basically take a laser engraver (the type with the fixed laser head and those 2 spinning mirrors), point it at a high voltage drum, lase the pattern (removes the charge from parts of the drum), add the toner power and then roll over paper. For color just replicate that x3.
I think a Opensource Black/White laser printer should be possible at a price point of maybe 600$ in components (3d printers also started out at that price point then got cheaper). I doubt it would be as quick as commercial models but it should be doable.
I think an open source paper cnc machine similar to a cricut would be way easier to replicate than a standard printer.
That’s a plotter, and opensource plotters do already exist. Problem with em is that they lack speed and precision to print small text.
Would you accept a printer that works like a typewriter with arms that strike the page to lay down text?
What about a 2d pen plotter? Not nearly as fast as an inkjet, but still open source
There’s some projects out there for those.
Plotters are problematic, due to them beeing very very slow and that everthing they print has to be converted into a vector first.
Fonts are vectors
I’m glad there’s enough comments to show I’m not the only one who has to look it up.
If I created a piece of art (despite having no talent but that’s not the point) could I prevent its image being reproduced by incorporating the constellation? I guess only on printers.
Ridiculous, inkjet ink is FAR too valuable to be wasted printing something as worthless as money.
Also if the money can be duplicated with a printer then it’s little joke monopoly money already, just give up statists !
I do not understand. Help?
Here’s the relevant wiki article:
Ah ok! I remember. Thanks.
I forgot about this for some reason. Shit I’m getting old.
so all i have to do is get the EURion constellation tattooed on my face, and then i can defeat surveillance cameras….
And a bumper sticker to forget about speed cameras.
Ok, but more realistically, could we have a war of all against all until everything is ashes ?
I don’t think anything less is going to be nearly enough.
Also we need to make sure none of the things that descend into the bunkers, ever, EVER come out to infect the surface again
Hmmmm
Now I want a rubber stamp with that to prevent whatever from being scanned.
me too
What the hell.
Let’s forbid reading anything with like 5 circles loosely together …
what
Pattern of symbols incorporated into a number of banknote designs. Many printers, scanners, even software will prevent loading the document for processing if the constellation is present.
Doesn’t the money printing lockout require more than one instance of it?Depends. On some machines the five rings are enough.Otherwise random chance would have printers detecting it in all sorts of stuff.
Also it’s not a real star constellation. It’s a portmantou of euro and orion but the pattern is not the same.
Wtf is 5 rings besides Olympics
