I've looked through a numer of 'solutions' to this problem, on this website and also on Microsoft and other places, non have yet provided a definitive solution. Canon should be ashamed of themselves for allowing this issue to go unresolved for so long. I for one, will never be buying Canon again.

why is this still an issue... every other week I get this error.

takes an age to fix... never the same fix...

Open elevated cmd prompt (as administrator)

copy & paste as below

1 enter:      <net stop spooler>

2 enter:        <del %systemroot%\System32\spool\printers\* /Q>

3 enter         <net start spooler>

should work on all printers.

I tried this fix multiple times and it still gave me the "Another computer is using this printer." message.
I was really hoping that was the magic bullet.

I've tried several things but think I've come up with a consistant way to correct the problem. I say this because my solutions seems to always work.  What I do is Reboot the wifi and or routers appear to always work.  Now as far as a permanent solution I dont claim this to be. After rebooting, the printer will work without the "Another computer is using the printer" error for several hours or days but as of yet has not been the fix all.  Not sure what the issue is as it could be spotty wifi or internet but I'm guessing the internals of the print software sometimes doesn't always send and end of job message to the print service.   If this doesn't work for any of you, let us all know but I do know its solve the problem for me immediatly over several months and seems to last for awhile.

I just had this occur recently, and it's 2018!!!  So,  first i tried changing the spooler setting which didnt work.  then reset the router which didnt work.  then reinstalled the dang printer which is a pixma and just a year old.  that didnt work.  then,  went ahead and put in new ink cartridges, and lo n behold the dang printer started printing stuff i'd wanted all darn morning!!

i have window 8.1,  but it also affected my other computer which has win 10.  this is no doubt a darn software problem with canon and they are not either fixing or letting people know how.  But,  the darn thing works now,  so try what i did.

CR68, Thanks for your response. I’ve replaced ink cartridges as well and had the printer work but it would happen again a few hours or days later.
I have another theory and think this might be the culpri. I print from my iPhone or iPad as well as laptop. Both are connected via Wi-Fi. The iPhone/iPad connect via 5g and the laptop via standard Wi-Fi. I think the issue happens when I print over 5g and the laptop tries to connect after that. To print I now connect to standard Wi-Fi to print and have not had any issues since doing that. Hope that helps.

And what do you do if no printer WITHOUT the WS is showing up in your Printers and Devices? I don't have any other option apart from the WS one....

Hi,

I registered just to post this solution I stumbled on after months and months of pulling my hair out, and no help from canon.

1. log into the printer with the ipaddress and any browser

2. click on advanced

3. click on other settings

4. increase the WSD timeout setting (im using 10min)

Everything is working again, the printer was timing out 

I hope this saves everyone alot of time and trouble.

Also my printer is a MX522 but I assume it would work for all pixima printers.

Thank you! This did the trick. Glad I found your solution so quickly. Back in business!
