Re: mx 922 often says "another computer is using this printer" and won't print.

I am running Windows 7 Home Premium on 2 machines.

All updates applied to Windows 7 as of today

Both machines are ethernet connected to wireless router

MX922 is running wireless to router

MX922 drivers are current per Windows Update

Problem occurs frequently but intermittently on both machines

Fix appears to be restart machine from which printing is attempting.

Restarting network, printer or other machine does not resolve problem

Problem is recent occurence (past 1-2 weeks).  No similar problems in prior 6 months.

 

As a test, I would like to revert back to prior drivers but I do not know how to do this for Canon MX922.

 

Thanks for whatever help or suggestions you can provide.   -Bob

Dreamstalker, what do you mean that "my computer made a second printer".    -Bob

Re: mx 922 often says "another computer is using this printer" and won't print.

I managed to fix this a few days ago though did not update my previous post in case the problem cropped up again.

However, it all seems to be fine now. I am running Windows 7 64-bit and my printer is MG5460.

 

Okay so, from memory, what I did the first time was (note this didn't solve the problem, but may still be relevant):

  • I manually removed the printer (Control Panel > Hardware and Sound > Devices and Printers > right-click printer and select "Remove Device").
  • Uninstalled the Canon printer drivers
  • Installed the MG5400-series driver package (downloaded from Canon site)
  • Re-added the printer using the built-in  'Add a Printer' tool that Windows provides

This worked initially but the error reappeared the next day.

The next method I tried fixed it (again, I'm going from memory here):

 

  • I re-configured the printer's WLAN settings (probably not necessary as it was already connected)
  • After having no luck, I manually removed the printer again from 'Devices and Printers'
  • Then I re-installed the entire package (drivers and software) directly from the Canon setup disk.
  • Also I turned off printer sharing in the printer's properties menu, though I can't remember at what stage I did this.

One of my mistakes before, I assume, was using the built-in 'Add a Printer' function instead of installing direct from the disk. My advice is just install from the original disk (even if it's outdated, it at least gets it working).

 

Final thing. I'm not sure if this is relevant, but I noticed when I installed the printer using 'Add a Printer', the port name was different. It started with "WSD-..." and the description was "WSD Port". When I installed with the disk, it assigned the port name "CNBJNP_....." and the description is simply "Canon BJ Network Port".

(The port settings can be viewed by right-clicking the printer > select 'Printer Properties' > 'Ports').

 

Hope this helps in some way people still having the same problem!

mtRoom, thanks for the good info.  Especially about the port naming. 

 

I have the problem and I have the "WSD..." naming.  You've given me an idea about reinstalling and watching the port assignments.   I'll post back with the results.

Re: mx 922 often says "another computer is using this printer" and won't print.

mtRoom, you provided the solution!

 

I removed all traces of the printer on both Windows 7 machines.  Then I reloaded each machine from the original Canon MX922 disc.  It created ports that began with "CNJN..."   I have tested extensivley and it seems to be fixed. 

 

What I do not know is how the ports beginning with "WSD.." were created in the first place.  It may have come from allowing Windows 7 to install the printer (instead of using the Canon disc). 

 

After installing fom disc and testing, I ran Windows Update and I see an optional update to the Canon SW recommended by Microsoft.  This could be how I got into trouble the first time, since I remember performing this update a month or two ago.  I may pass on this update for awhile.  But even if I allow the update and it it gets me into trouble, I now know how to fix the problem.

 

Thanks again mtRoom.

 I have uninstalled and reinstalled it about 20 times.  I need another solution.

I click on "I agree - install firmware" and nothing happens.

Re: mx 922 often says "another computer is using this printer" and won't print.

I have just bought an MG7150 and got it up and running no problem.  Then suddenly I get a message saying "another computer is using the printer" and it wont print any more.  I am running windows 7.  I have read the other comments, but do not know what to do to get it working.  Can anyone help please?
