Go back one page, or click on the "Administration" button in the page's menu bar, then click on "Find new printers" and report the result.

Try this:
Enter localhost:631 into the address bar of your web browser.  This should bring up the CUPS page.
If it does:
Click  on the Adding Printers and Classes button. 
Click on Manage printers

Let me know the result.

Have you ever had this printer working on your Linux computer?

The error message is not encouraging.   
Please paste the whole output of the sudo lpinfo -v command.

Hi Don.

You've probably done this, but I show it for other users in the same boat......
1. Go to https://support.brother.com/g/b/downloadtop.aspx?c=gb&lang=en&prod=mfcj6930dw_us_eu_as
2. In "Step 1 click on Linux.      In "Step 2" click on "Linux (Deb)".     Click on "OK"
    This will get you to https://support.brother.com/g/b/downloadlist.aspx?c=gb&lang=en&prod=mfcj6930dw_us_eu_as&os=128
3. Under "Utilities" click on "Driver Install Tool"
    This will get you to https://support.brother.com/g/b/downloadend.aspx?c=gb&lang=en&prod=mfcj6930dw_us_eu_as&os=128&dlid=dlf006893_000&flang=4&type3=625
4. {Clicking on "Compatible Model" shows that your printer is indeed supported.}
5. Scroll down to the bottom then
6. While holding down the Shift key, click on the blue "Agree to the EULA and Download" key to download the drivers.   
    This will get you to https://support.brother.com/g/b/downloadhowto.aspx?c=gb&lang=en&prod=mfcj6930dw_us_eu_as&os=128&dlid=dlf006893_000&flang=4&type3=625 and also open a download dialogue box. 
7. Select "Save" and "OK".  This will save the compacted file that looks looks like "linux-brprinter-installer-2.2.3-1" to your usual download directory (usually "Downloads") - make a note of the file name.
8.  The dialogue box will disappear to show the instructions which you should follow.  Replace the "*"s with the numbers in your file name.  If the command fails then prepend "sudo" to your commands.  (More detailed instructions are also here: https://help.brother-usa.com/app/answers/detail/a_id/52188/~/install-drivers-%28deb-or-rpm%29-using-the-driver-install-tool---linux)
9.  You will be asked for your printer's URI.  This is your network's address of your printer. You can get this from your printer's menu system or from a terminal command sudo lpinfo -v" where you look for something like network socket://192.168.1.73:9100. Ignore "network" and copy the rest.

I don't have a Brother printer so can't guarantee the result, but let us know how you get on.  By the way, to avoid confusion "lpinfo" is lower case for "LPINFO".

Hi Nogueira.

UI is really GUI: "Graphical User Interface" - just the window that you see on your screen.
 
The scale factors mentioned on your link don't exist on my Ubuntu system, but you can check yours by issuing the following commands:
Code: [Select]
echo $QT_SCALE_FACTOR
then
Code: [Select]
echo $QT_AUTO_SCREEN_SCALE_FACTOR
then
Code: [Select]
echo $QT_SCREEN_SCALE_FACTORS
If any of these results in any text (rather than a blank line) then you might be in business.

Broadly speaking, I rarely change environment variables, and you are right to be wary. 
My own solution to inconvenient text font sizes (which seems to be a more frequent problem these days) is simply to use the Ctrl++ method to increase the size.  That is:  while holding down the Ctrl key, tap the + key as many times as necessary to increase the text size to whatever you want.  Use Ctrl+- to reduce the size.   
Hope this helps a bit.  Best I can do.

Linux Support / Re: Chrome Update for Ubuntu Macbook help needed please!

That looks good.
Just to tidy up first - use "autoremove" to dispose of code it no longer needs:
Code: [Select]
sudo apt autoremove
Now enter these last two commands of post #10:
Code: [Select]
sudo apt remove chrome
and
Code: [Select]
sudo apt install chrome
and post the output. 

Re attachments: we trust established Members! You can attach images, too, but please reduce them first.

If your computer update repositories are set up with one for Chrome then this should work:
Code: [Select]
sudo apt update
then
Code: [Select]
sudo apt upgrade
(It will update everything).

If that doesn't work, then re-install Chrome as in your other post.

You forgot to update before upgrading - unless you did that but didn't post the output.  Try
Code: [Select]
sudo apt update
then
Code: [Select]
sudo apt upgrade
Shouldn't take long.

Then, if Chrome is the only problem at present, try reinstalling it:
Code: [Select]
sudo apt remove chrome
then
Code: [Select]
sudo install chrome

By the way; you can attach long output as a file, which makes the Forum pages easier to read.

Is this the same as your post Need to update Chrome browser on my Peppermint Netbook? Or your ChromeBook? 
It would be helpful if each post you make is for one machine, giving details of operating system and the specific problem etc. 

If your updates are very out of date, then it might be easiest to delete then re-install the Chrome browser. 

Thanks.

HI Matilda.

Is this on your MacBook?

Hi Tanger.

I'm please that you've solved your problem.  If you are happy that it's all done, please edit the title of your first post on this topic by adding  [SOLVED] at the end.  This will help other people to find your solution.

Thank you.

Hi Rincon.

I can't help you with Wordpress but I can tell you how to attach an image, or any other file. 

1. reduce your image size to less than about 200kBytes (very important)
2. Just below the text box where you write your text, you will see the words Attachments and other options.
3. click on that phrase (or the "+" box beside it) and scroll down a little.
4. then click on the "Browse" button, navigate to your chosen (reduced) file and click on it.
5. Done!

Your method of adding a link to were you have uploaded the file is good as it doesn't take up space on the Forum's server!
Hope this helps.

Keith

Tanger,
I've used neither the PI computer nor a pH meter, so can't really advise you, but here are my comments on the two that you suggest:
  • I note that the Atlas Scientific EZO has a pH resolution of +/-0.002 - do you really need that high resolution? It costs $42 and seems to require a separate probe that you will have to buy.  The circuit board looks a bit rough.  The websites that I've searched for this product say it is not available at present. 
  • The DFRobot is about the same price but comes with a probe.  The pH resolution is only +/-0.1 which is probably OK for most people (only the user can decide that) and the whole assembly look very professional.  I note that this product is still available. 
Hope that helps a little.

Sorry, Tanger - I have tried Wordpress just once and hope never to use it again!  I find writing HTML far easier. 
Some utility software have a "reset to default" somewhere in the menus, although I expect you have already searched for that.

So I can't offer you any other advice this time.  Perhaps other members can help. 

Keith
