How do I use a printer without an Internet connected computer either connected to or integrated into it?

If you don't want to go the USB route, put the printer on its own separate VLAN and/or Wifi network and filter all outbound traffic from that network at the router unless (1) part of a connection initiated from the other side and (2) aimed at another local host. Filter traffic going the other way (opening those connection) to taste - perhaps allow access only to the IPP port and certainly don't allow any inbound traf…

Another problem is if the update is packaged in a print job, which seems to be an option according to comments here. In that case, the Internet connected computer may still be hijacked by the manufacturer to bork the printer against the customers will, by sending a malicious print job to the printer.

I made the mistake of buying an HP printer years ago. But I found a 'neat trick'. You can subscribe to the free Instant Ink program using a test credit card, i.e. a number from https://developer.paypal.com/docs/payflow/payflow-pro/payflo... . And ~2 days later you have ink sent to your door. Fuck you HP.

Isn't that credit card fraud?

I bought an original HP cartridge for my Laserjet printer because I read that 3rd party cartridges may have issues with displaying the amount of ink left. Everything was all fine until the other day I did some cleaning on my desk and put my printer on the floor for 15 minutes. Since I put it back on my desk, it has been complaining that the cartridge is close to being empty, whereas it should be at about 70%. I remov…

There is no level sensor in cartridges. It simply counts pages and time. After a fixed number of pages, or a fixed number of days, it says "ink is low".

There absolutely is a level sensor in many toner cartridges these days. Are you still using a 90s model LaserJet?

> Why would you buy an HP printer and try 3rd party ink, when you know the whole business model is subsidizing the printer and selling you expensive ink, and you also know that the whole printer cartrige space is full of DRM roadblock? The vast majority of people don't know this because HP spends tons of money on marketing to distract consumers from the fact that they do this. Stuff like this is why consumer protecti…

consumer protection is just a workaround / band-aid on proper advertising laws. Corps can take massive liberties on promotion, then CP needs to negotiate where "too far" wrt misrepresentation is. How about product categories have mandated upfront declarations, e.g. DRM / no-3rd-party printers need to state as such, in an unambiguous way on the box in some mandated-minimum font size.

That sort of stuff falls directly under the "consumer protection law" umbrella.

Return it for a refund and buy a different one. Otherwise, how will HP and the shops selling this crap learn?

If it’s outside your return period, you’re SOL usually. You may have a civil case over what could be argued as “crippling” the product, but it wouldn’t be as easy.

It's probably a small claims court matter, and those usually side with the customer.

That proprietary plugin for scanning provides WSD and eSCL (AirScan) support. However, your distro might use recent enough sane and sane-airscan, that does support these protocols. Due to recommendation here on HN, I've been checking Brother laser printers. They also require installing a proprietary package from the manufacturer, and a proprietary tool for the print queue setup.

I've tested two HP laser all-in-one models (MFP series), and the scanner did not work at all without the plugin. But I have no experience with other models.

HP Color LaserJet MFP M181fw here.

Year ago, the plugin was needed for the scanning. Today, it works out of the box with Fedora 33, no plugin (I'm using eSCL mode).

Fedora 33 ships with sane 1.0.31, sane-airscan 0.99.18 and hplip 3.20.9.

I remember coming across forums long ago (at least 15+ years) where some friendly hackers had figured out how to patch out checks like these and posted modified firmware for various printers with features like "cartridge always full" and "automatic waste ink reset" (mostly applicable to inkjets with CIS instead of lasers), and this was at a time when it wasn't that easy to change the firmware of a printer (which is frankly quite scary). I have long lost the link, and I'm not sure how much of such communities exist anymore, but that was an interesting discovery that, for a few days, I spent many hours reading.

Mine doesn't have the allow downgrades option I think. But this worked for me: > "Unplug printer’s power cord from the back of the printer Press and HOLD the power button Plug power cord back in (keep holding power button) The HP logo will appear then the screen will go blank Hold power button for 10 seconds and then release it Press HOME BUTTON ONCE (top left) Press RETURN/BACK ARROW ONCE (bottom left) Press HOME BU…

How do I use a printer without an Internet connected computer either connected to or integrated into it?

If it's networked, just manually add an IP address and don't specify a gateway.

Is that a more recent thing for Brother? I have one (probably c5 years old) and although there are proprietary drivers if you want them, it will happily accept PCL or even PostScript (PostScript is slower though) over IPP and it has a basic interface on its http port (toner levels, page counts, etc). It wasn't the lowest-end model but it wasn't super-expensive either. I think the next model down was the same but woul…

I was checking Brother MFC-L2712DW and found this: https://support.brother.com/g/b/downloadlist.aspx?c=eu_ot&la...

Can anyone confirm, that this is not necessary and it works OOB with software shipped with distributions? (I need it to work with Ubuntu 20.04 and future LTS releases, preferably without anything that would bite me two years down the line).
