Incorrect Workgroup Name

[JoHubb]

My wired LAN network is called WORKGROUP by Kubuntu. This is incorrect. How can I change it?

I am trying to connect a dual boot PC (W10 and Kubuntu) to my network printer.

I'd be grateful for advice.

Mine says Wired1. I think WORKGROUP is a Windows default? Right click your network widget and click configure network connections and I think you can change the name but I'm not sure that will fix a network printer issue.

Mine says Wired1 and a second one (??) says Wired2. I managed to change the name to the correct name, but I might as well have changed it to The Man on the Moon for all the difference it made!

I can access the printer via the router, get its IP, the status of the connection etc, but LibreOffice still cannot find it. It may be something to do with the driver. I installed the Canon pixma driver and this may be part of the problem. Trouble is I cannot uninstall it and go back to the default Kubuntu driver. At least, I cannot find a way of doing this.

Thanks for your help, anyways.

I'm not sure what you mean you can't uninstall the Canon driver. Under Settings>>>System Settings>>>Printer, do you see your printer? If so you can delete it and install it again with a different driver.

Yes, I tried that but I could not understand the options:



I am not even sure that my Canon printer is a 'network printer' as such, although I've been using it in a LAN for a long time.

I did a driver search, the result was that I did not need any proprietary drivers...

It wouldn't seem a very difficult ask, that Kubuntu can connect with a standard Canon Pixma printer. I can connect with Mint and W10 on a different PC.

What model is your printer? If it has a CAT5 cable plugged into a switch or router it is a network printer...or it may be wireless. If it is connected to your computer it is not and you would have to share it. I suspect you have to download and install the correct driver from the Canon website. There are plenty of instructions and You Tubes that tell you how. Interestingly many of them are for Mint so if yours installed automatically on a different Mint computer sounds like you got lucky. I use HP printers since HP supplies HPLip for Linux. Canon drivers may be less robust but I bet you can get it working.

Thanks again. The printer is a Canon Pixma ip7250. It is not a 'network printer' in that there is no CAT5 cable plugged in.

It is on the wireless network. Heaven knows which, if any, Canon driver will work for this in Kubuntu. As you say, I might have struck lucky with Mint.

Hopefully, I will get hooked up in the end, but things aren't going my way at the moment. Our broadband is down yet again (what is it about Virgin and Sundays?). We are now on a backup mobile hotspot - Virgin tech can't get here till Wednesday...wot a lark!

... Canon Pixma ip7250. It is not a 'network printer' ... It is on the wireless network.

IIUC, that's a direct contradiction. If it's not plugged in to the computer that Kubuntu is on, to Kubuntu it's a network printer, because Kubuntu uses the network to reach it.

IMO the network is usually the best way to use a printer. Even a printer that only has USB can be connected to a home router, but I imagine that's tricky to set up.

I wrote: It is not a 'network printer' in that there is no CAT5 cable plugged in. This was the context from the previous posting by wartnose. I simply made the point that the printer is on a wireless network.

Great stuff! I don't know how you tracked these sites down. I've been looking, but obviously not hard enough. Thanks!

I connected the printer to the PC with a USB. At least that way the PC can identify the printer. The wireless connection can come later - it will have to because the printer is normally 20 feet away from the PC.

I ran the downloaded Canon ppd for the ip7200 series but got this: File "/usr/lib/cups/filter/hpcups" not available: No such file or directory". I looked for fixes for this and tried one or two but drew a blank.

The good news is that the default CUPs driver appears to work alright - the test page seemed ok, but that is as far as I have got.

Ideally, I would like to install the ppd driver but why the error message refers to 'hpcups' is beyond me...

It seems that my network card is not compatible with Linux. (ASUS PCE-AC88 Dual Band 802.11ae PCI-E).

Not sure if this card can be 'tweaked' or if I must forget about printing directly from this PC.

Thanks. I tried this. In the end it comes down to installing/copying a new .bin file - brcmfmac4366c-pcie. This file is needed instead of
brcmfmac4366b-pcie. Unfortunately, I could not persuade Kubuntu that brcmfmac4366c-pcie actually existed, much less copy it to the required folder.



I wonder if my Kubuntu install is corrupt? Nothing seems to work as it should.

Are you sure that the downloaded file is in 'your' home directory (/home/howard/downloads)? You could, while in Dolphin, click the Split icon to open a second window, make it active and select /lib/firmware/brcm as the directory for that window, then click and drag the file from the other window to the new window. You will be asked for your password to complete the action.
