Could it not be provided in the form of a downloadable app, which could access documents via the content hub? -

The cups packages, PPDs, etc... all need to be in the rootfs, and it runs as a system service. Also, as click packages cannot provide services and such things, trying to shove parts of this into there will only be extremely messy and hard to clean up in the future.

Thanks for that, @dobey.

@3arn0wl So, in the meantime, we can use some workarounds. Several printers providers do offer remote printing solutions: Ex. Hewlett Packard and it's Smart print application, Canon and Brother with Google Cloud Print, etc... Some of them nevertheless need the installation of an app or software, which can not be executed with UT. Or the other way is to transfer files from UT to any cloud/drive.., than print it from another device.

I was thinking to another way to print: And why not send the file by bluetooth using the native UT app "bluetooth transfer" to a compatible printer? Than no need any spooler service, as printer do all the work. Could that work?

No. Bluetooth printing does not work by file transfer. Still cups would be required, to provide the print service which talks to the printer. Also, it requires extra integration to enable connecting printers from the Bluetooth settings UI.

@dobey Ok thank you. I admit my idea was a little naive...

Another workaround to print from your Ubuntu Touch device can be found here

@arubislander Thank you very much for this input. So basically create a libertine container and activate softwares (such as libreoffice) to communicate to printer network. As I’m newbie I’m not sure I have the technical knowledge yet to use libertine, but will definitely keep those instructions to do it later on.

Over in the Sailfish universe we have SeaPrint (by me)... so if someone wants to port it, feel free to get in touch.
No CUPS dependencies, strictly speaking no dependencies at all other than Qt, but poppler is needed for working with simpler printers.
