Recently bought a Canon 7720 and we have this very problem. What a nightmare.
We have 2 PCs and the printer effectively gets stuck in this "Another computer is using the printer..creating print data" literally ALL the time. Yes you can temporarily resolve by deleting printers/rebooting/restarting printer/waving your hands but what kind of a solution is that? And it just comes back the next time you want to print something.
This is pretty pathetic Canon....and its truly making me consider ditching this piece of cr*p and go for an Espon or something.
Seeming as this problem as been around for literally years one can only conclude that either
a) Canon simply don't care one iota about their community
b) They are completely clueless about the resolution of the problem

I have a long history of struggling with printers. My second-to-best weapon is to restart the print spooler service (the best is to restart everything, including including the pc and the printer). I've just used it to solve the issue discussed here (I have a Canon Pixma MX535).
Here is how you do it: https://www.youtube.com/watch?v=fjNpty4tbls
Note 1: it is easier to get into the services window by bringing up the task manager with ctrl+shift+esc, navigating to the services tab, then opening the target window by clicking the link in the bottom of task manager.
Note 2: if you are using Windows in your native language (other than English), you might look for the words corresponding to "printer" and "queue" if you don't know what "spooler" is.

I also have it on the IP7260 and in both offices where there is an M range printer in each. We have taken to not using wifi between this problem and a pretty flaky wifi anyway on the m range in the offices.
We now have this on the IP intermittently, fortunately I only print intermittently.
However, the decision has been made at the next replacement, we will not be replacing any printer with a Canon. We're not a big user, hardly going to hurt Canon, but its time to walk away and find another solution.
I will see if there is an updated driver under Windows 10, but unless that fixes the problem, we'll just walk away.

Solved here !!!
I've been also impacted by the blocking error message with a MX535 multifunction:
"Another computer is using the printer"
As there's no menu in this multifunction to reset the device, the simple solution that solved the issue for me was to:
After it has restarted, the message "Another computer is using the printer" did not reappear .
BTW, some precisions with drivers stuff for these WSD printers:

MX922 having the same problem for months now. Why doesn't Canon offer a solution?
We have eliminated all the WS duplicate printer devices from our computers. Problem is highly inconsistent. On some laptops, it will sometimes go right through. Sometimes we need to turn off and restart printer. Sometimes nothing works, but then we might find a printout a day or 2 later.

Thanks raffia, for your advice on this issue. However, your advice contradicts most of the previous messages which recommend eliminating the WS devices because they seem to get jammed up with print jobs that don't go through.

Hairetikos, I've given some additional information here about WSD services, and how this technology can be used with WSD printers.
I've posted it as many people seem to ignore this feature, and I find it to be pretty useful to use as it greatly simplifies the installation of a new printer: no installation required.
Additionally, reading your previous post, I understand that the original issue in this post is not solved by attempts to hack the WSD driver in Windows, it seems to affect both WSD and "legacy to be installed" drivers, as the root cause is certainl a bug in the printer firmware, not fixed by Canon. Hopefully, we can be turnaround it by a simple manipulation on the printer.

this totally worked. Thank you!!! I had 3 different printers set up under my Canon Pixma pro 100. Not sure why but it had to be a canon default setting, When I changed the default printer to the canon Pixma pro (without the WDS) it worked and I was able to print without the irritating message popping up that prevented me from printing.
Does anyone know what the WDS printer is for anyway?
