Yes, fingerprinting on the paper are not prevented. The question is if there still is some kind of fingerprinting which is not indended on such a Purism printer. Like on typewriters.
But if its in the network its also not just about phoning home but also a potential point for hacking. And then a base for further attacks in the network.
This already get prevented with the offline option. So already a good step to get a more secure environment.
It should be named Neo,
print in DejaVu Sans in ASCII mode
and have a red pill power button.
Display reads “Matrix: Reloaded” after standby.
No full duplex mode. Trinity mode instead.
Built-in EMP-hardened squid proxy.
Easteregg: replaces the string “Alice in wonderland” with “follow the white rabbit”
Wow. 20 years.
But quite fitting for a privacy respecting printer; )
Can the dot matrix be 6x7?
Given that ink toner cartridges have no clear standardization, how is it that Librem can use a form that will be other than its own proprietary form. If so, do they want to get into the manufacture of this business? They certainly cannot readily use a unit form of HP, Epsom, Cannon or Brother or the countless others such as Lexmark that are in the market.
A Librem printer could try to opt for some port access of a bottle to fill some built-in reservoir, but this would create some whole new set of problems for cleaning and dislodging junked-up and gelled material.
So FOSS printers would be very useful for whistle blowers. They could be able to print a document without machine identification codes. Maybe it would be possible to drive it a step further and print fake codes to lead their hunters onto a wrong track. Some basic work on decoding has already been done:
Hunters would have to go further, too if they want to trace someone via the printed document like analysis of the ink or individual laser density during print.
In general a whistle blowers printer should be as mainstream as possible to hide in the mass. For non whistle it maybe best to just don’t print any code or special individual detail at all.
It can be good to set the default gateway on all printers to be a bogus IP address, assuming that a) you aren’t using DHCP for the printer, and b) you don’t need any printing functionality from outside your LAN.
I have Brother monochrome laser printer with scanner, comes with USB, brought it several years ago, it wasn’t expensive, even included a toner. Works on Linux. I brought an extra toner for like 20 bucks at that time. I just replaced toner a couple weeks ago as that first toner last me several years of using around thousands of pages.
Ink cartridges always dried up by itself after several months even if you don’t use it, but not toner for laser printer. There are competetive prices for toners at Amazon and Newegg. As for HP, Canon, Lexmark, and Espon, they are crap, I’m not comfortable with them due to their unethical business practices.
