Environment:
Canon MP230 connected to a raspberry pi with CUPS installed.
I'm able to print without any problem using 2 different PCs and an iOS device.
The app was tested on a LG Spirit H440N with stock OS (Lollipop) and root permission.

Description:
After installing and setting up the app was able to correctly detect the printer and send a file to print. The same file could be printed more than one time without closing it. After switching to any another file the printer was still correctly detected but after a while an error message claiming that the printer wasn't ready to print appeared. Deleting the app data or rebooting the service and the device didn't help. However reinstalling the app let me print again one file, after which the issue recurs.

Maybe this is already on your roadmap? The Jon Freeman Version is in f-droid but quite outdated and unmaintained.

Hi,

Thanks for putting this code on git hub. I have a canon MF210 printer that support IPP/IPPS. I have also shared the printer from my MAC. So when I install the android cups printer service on my device, I am able to detect the printer as well as the shared printer of my MAC.

I am able to send print requests through the shared printer of my MAC. But when I select printer directly I am getting 404 error. If I try and pass only the printer ip as url ( instead of http://ipAddress:631/printers, I am getting 406 error( not accessible error). Could you please guide me what the issue could be.

Bonjour,

Tout d'abord merci pour cette application sous licence libre.
Je m'exprime en français, merci de me dire s'il est préférable de discuter en anglais ici.

J'ai installé mon imprimante Brother en la branchant sur le port usb de ma livebox.

Les deux ordinateurs de la maison y ont accès, sous linux, selon le chemin

ipp14://192.168.1.1/ipp?version=1.0

et cela fonctionne (la config est documentée ici https://doc.ubuntu-fr.org/livebox#livebox_play )

Depuis l'application AndroidCupsPrint, je n'arrive pas à voir l'imprimante par la recherche automatique (cela dit depuis les ordinateurs linux non plus, j'ai dû entrer l'URL à la main).

J'ai tenté de mettre le même chemin, mais cela ne fonctionne pas. Peut-être que la version de CUPS n'est pas la même ? ou autre chose ?

Bref je ne sais pas comment faire reconnaître l'imprimante du coup.

Pouvez-vous m'aider à y voir clair ?

Merci

Hi!
I am using ACP with Android 5.1. Printing works, but the printing notification in the status bar stays forever. I have to cancel to get rid of it.

Hi

Thanks for this app. And sorry for the vague title.

I have a wireless printer that has its own server and also this printer shared over a Debian Pc via the Cups server. This app finds the wireless server but no printing happens(tried with firefox page->printing). When I select the printer I see no "print" icon however I have the brothers own print plugin that seem to work.

Also it cant find any Cups printers on the network like the one I mentioned above. I have a Pdf printer that is shared over the network via Cups, that does not show up either. I also tried putting the ip addresses and the printers as I would do over with other pcs, that does not work either.

Lastly The search button does not work when I enter the add printer option. It is not clickable at all. I tried putting custom ip of the server without any suiccess.

thanks

I have the following issue: The printer is detected, but it is "currently not available". The logcat shows the following two entries:

In the CUPS webinterface the defaults are shown as follows:

Like the title says. In the actual print dialog, when selecting the printer, it says the printer is currently not available. No obvious indications as of why. (Android 6.0.1 to CUPS/Debian)

Building/assembling works but when querying for printers the app crashes.

Workaround: Resurrect JfSSLScheme.java class and add

android {
    useLibrary 'org.apache.http.legacy'
    ...

in app/build.gradle.

But I guess the workaround is not the outcome you were aiming at...

From my Android (CM13), the printer (SCX-3400) is detected but when I want to print, I have this error:

Can't create handler inside thread that has not called Looper.prepare()

Then This printer is not available.

The printer is not wired to the computer with a USB cable, it's on the local network with Wifi.

I don't know if this is an SSL issue or a reverse DNS issue. I can print over WiFi from another unix box and I don't get anything like this. As far as I know I'm not running SSL at all (no reason to). Reverse DNS, well, I have my HP printer plugged into (USB) a Raspberry Pi, which connects by WiFi to an Android phone's WiFi hotspot. The phone's in control of DNS and DHCP.

Your app is apparently trying to do something unnecessary and it doesn't work. I'm not sure what.
It's the version that's currently (April 7) on Google Play.

I'm also at [email protected], just happened to have a github account and be on a CUPS mailing list.

Add a UI to manage self signed certificates for printers over https.

Seems to break things:

Turn on service, answer "OK" to security question. Device then starts "Searching for printers" - if there are no appropriate servers on the network, it will search forever. Using the Menu button, add a printer using the format shown, e.g. "http://192.168.1.111:631/printers/hp_thinkjet" (I copied and pasted the text from my working CUPS device). Select "Add printer" and return to the still-searching screen. The printer is not added.

SUGGESTIONS:

1. Add a "Stop" button to the search screen, to allow the service to continue running without searching for new devices.
2. Make the (manual) "Add Printer" function work, whether or not the service is searching for new devices.

Hello, F-Droid packager here.

F-Droid is an Android app store exclusively for open source apps. See F-Droid's Wikipedia page.
You can browse the catalog of available apps on Fossdroid.

I want to update the newest version of the app for F-Droid, and I've seen that you recently added crashlytics, which is a proprietary library. F-Droid forbids proprietary libraries.

It would be really great if you could provide either a custom gradle flavour that doesn't use crashlytics, or use a free alternative to crashlytics like acra.

Thanks for your help!

Hey, I just downloaded your app from Play Store and I'd like to ask (if answer is 'No' I'd also like to ask for such a feature/support) if CupsPrint support passworded printers?
I enabled remote access to my CUPS server (in order to for example restart printer remotely or fix something in cups when I'm not at home) but I put a login requirement since I do not like people looking/messing in my stuff. So the conf is looking like this:

<Location />
  AuthType Default
  Require user @SYSTEM
  Order allow,deny
  Allow all
</Location>

As far as I see CupsPrint do not understand(do not add printer at all)

http://login:password@ip:port/printers/myprinter

but it works when I leave cups webpage unprotected(which I dont like)

Several users reported the need to manually add a CUPS server, for those who don't use mDNS.

Hello,

I am trying to use AndroidCupsPrint on a Samsung Galaxy J5 with Android 6.0.1. Unfortunately I can not print at all.

Bellow you can see the error from CUPS error.log

E [28/Jan/2017:10:11:17 +0200] Unable to encrypt connection from 192.168.1.54 - A TLS fatal alert has been received.

This is on a Debian 8.7 with cups 1.7.5

Thanks

I have a setup where I have ten printers plugged into a single CUPS instance. However, only two of them show up when the AndroidCUPSPrint plugin searches for local printers.

This is with the current 1.3.1 release (obtained via f-droid), running on CM12.1 (Android 5.1.1) talking to a CUPS 2.2.0 server. All printers are exported/shared, and Linux desktops see them.

Why ten printers, you may ask? I write printer drivers (Gutenprint) for fun and occasional profit.
