Ok, I have a web browser on a locked down device and nothing else: how do I print a pdf or a photo using IPP?

I have: a camera, a browser, a file manager (kind of, think of an iPhone or some stock android business device) and I need to print a photo taken with the camera or a pdf file sent to me via email or WhatsApp?

The device is connected to the WiFi guest network with limited internet access (if any) and as only available service a server with port 443 open (a reverse proxy on that, captive portal and such).

In my experience, there is no way to print via cups in this configuration. Maybe I am wrong?

It still requires the device to be capable to print…

And the user to find the printer select it and so on. And must expose more ports on the network beside 443…

So, indeed cups is a great solution, but not to the problem I want to solve.

I do use cups in fact for the trusted part of the network, driverless printing for windows and Linux. Android doesn’t even need cups since it picks up the printer directly from the printer itself (AirPrint or whatevee that’s called).

I known cups can share printers and queues.

What is unclear?

I don’t want to pull drivers or install cups on devices. I want to print from anywhere just uploading a file to a web page.

If I have lots of devices or just want to let somebody print from his phone/tablet without installing or configuring anything…

With cups I still need to touch the system or the device somehow to let it print.

Yes, this is what I am afraid of… There is nothing out there for this task.

Hope to find something or maybe try to create something using lpr on the background… But this is the las hope as I have little time.

I want to print from a web page: upload the file, hit print button.

In this way I can print from whatever device I want even without any driver installed or configuration.

Yes, sure I am… Would probably prefer a bash CGI because I like challenges :)

(Author and such would be managed by my reverse proxy)

But I would prefer something already baked if it exist

You get a real IP? Its been cg-nat with every provider for the last many many years in Italy.

I got a cheap vps and just run some reverse tunnels to map ports from it to my home server going trough my cg-nat.

Don’t. Backup data, reinstall software.

Answer.

I am not sure that checking the time in the watch instead of on phone counts as reducing phone usage…

But anyway, any “smart” watch will not help you as they all need a phone app.

Get a cheapo analog watch, in that case…

Well, my experience is that unless you set static IP+DNS in android WiFi advanced networks, it will not obey the dhcp option 6.

LineageOS, vanilla with mind the gapps

Yes, perfectly… My guess is android bypass local resolver and goes via DoH l, which sucks hard

As sport watches go, get a Garmin. Its proprietary, but it’s the best in the class.

I have a Fenix 7, wife has a Fenix 5.

Battery last days/weeks (5/6 days with some 10-15 hours of sport tracking with GPS active).

I suggest some “older” models with MIPs displays, not AMOLED, because they have better (absolutely perfect) under the sun readability and much better battery life.

You need the Garmin Connect app on phone, but the web interface to the Garmin ecosystem is simply the best.

I managed to integrate Fittrackee (self hosted) and synched to my Garmin profile to keep all my activity self hosted.

Despite being proprietary, Garmin software is quite nice and the watch can be connected directly to PC to download activities and tracks even without using the app.

Old thread, but I have somehow solved by reinstalling unbound and nuking the old config file…

Thanks! This explains a few things… But not why Android is IGNORING my DNS pushed via DHCP even if private DNS is disabled…

It’s blatantly ignoring the DNS i set via DHCP it seems. Only if i set it manually (static) it will use it! I have no subnets

Private DNS is disabled.

And even ping from tmux fails…

Latest build had issues with a few models due to a selinx issue.

Flashing an older build should work tough. Try flash a selinux-permissive zip from recovery maybe, that should let you boot.

Next week build will fix the issue I am sure, but you should join the lineageos reddit channel or the discord server.

Install some DNS test app for Android and check that it does get resolved.

My will resolve the home server address to 0.0.0.0, and I get the same network error.

I have a very similar issue. Seems like Android will bypass your DNS resolver and thus cannot resolve your local names.

I have my home services on “home.my domain.com” accessible from outside and re-mapped to “192.168.0.1” (my internal server IP) at home, and all PCs can access it while all android phones can only resolve to the public IP.

I feel it’s something related to DoT or similar but haven’t yet dig in that.

Been using USB since forever. I have one USB3 jbod with four SSDs (2 RAID1 + 2 RAID1) and an USB-C double enclosure with two spinning disks (RAID1 as well)

Setup is running flawless since 2016 at the very least, but I was using USB even before that timeframe.

All the RAIDs are Linux software RAID.
