Question Questions about Mopria

[kenwood850]

I have reviewed the mopria.org website, including the FAQs, and find there is quite a bit of confusion on my part. Perhaps someone here who is familiar with Mopria can straighten me out by answering these questions.

1. The mopria.org website talks about it being a service and some Canon printer descriptions indicate that an Internet connection is required to use that particular printer. Both of those facts imply Internet might be a requirement, but I could not find anything that actually said Internet is required on the website. As a result my first question is, once you have your printer up and running using Mopria, do you still need an Internet connection, or can you use the printer on an air-gapped private network?

2. The website seems to indicate that Mopria will only work on wireless networks. I am not sure why the medium for the packets, wired Ethernet or Wi-Fi, would make a difference, but assuming that is correct, do both the computer and the printer have to be wireless, or can only the printer be using Wi-Fi?

3. Some Canon printers that indicate they support Mopria have a disclaimer that also indicates that Windows 11 operation is only guaranteed for pre-installed Windows 11. I am making a big assumption here that this disclaimer has something to do with Mopria, If that is the case, are the Dells et al. of the world adding something to Windows 11 that supports Mopria that you do not get with a user installed Windows 11? If so what is it, and can it be added to a white box Windows 11 PC.

Thanks.

Found this:

The Mopria Print Service for Android was released to the Google Play Store in October 2014. It is a plug-in that enables printing from Android devices to Mopria certified printers and MFPs.

A client uses mDNS to automatically discover a printer through the local 802.11 wireless network. The printer must be connected to the network either wirelessly or with an Ethernet cable. Mopria Print Service also supports printer connection through Wi-Fi Direct.

I too have Canon printer, namely Pixma TS8352 and mine is connected to my home 5Ghz wi-fi network.
And for software, i'm using: Canon Easy PhotoPrint Editor,

So, i don't think that PC has to be connected to wi-fi. E.g my rig is connected to my router via Ethernet cable.
Also, you don't need the printer to be connected to wi-fi either. Printer comes with cable to hook it up directly to the PC.

that Windows 11 operation is only guaranteed for pre-installed Windows 11

Well, if WIn11 isn't installed, how it can operate via Win11?

that you do not get with a user installed Windows 11?

I think you got it mixed up. For it to operate under Win11, it actually needs Win11. Doesn't matter if it is SI or user installed. As long as OS is installed. E.g it isn't preview version, but instead full installation.

Based on the second paragraph of your source, it would appear that Internet connectivity is not required for actual printing. I guess I will assume the Internet is a requirement for the availability of drivers or other software. Either that or it is their way of indicating that the printer needs to be on a network to work, at least in some cases.

Also based on the second paragraph, I did some research into mDNS, and since I do have a Raspery Pi running Pi-hole, I can try installing avahi on the Pi if printer connectivity cannot be established out of the box.

Good to know. Your experience is a better indication than anything that the manufacturer or standard might say, and I will certainly look into your software recommendation.

Good question, and since the answer is obvious, why make a statement that Windows 11 is required if you are going to use Windows 11?

I would think using the term “pre-installed” is a red herring in this instance if that is their intention. The only times I have seen that term used in pre-sales descriptions for any device is to indicate that the manufacturer has installed any needed software so you do not have to after your purchase. I would think if they felt the need to be sure that a beta, preview, or similar version is not going to be used, it would make more sense to use a term similar to “requires a production release of Windows 11.

The bottom line is that it seems the ultimate answer is to order the printer from a source where it can be returned if doesn’t work as they say it will. I was trying to avoid the possibility of a return, but since “the proof is in the pudding”, you first have to buy the pudding.

Thank you very much for replying. I know it took some of your time, particularly since you obviously also did some additional research to find things I missed. Your comments are really appreciated and any appearance of criticism is directed at the source and not you.
