Canon MX850 Driver for 10.6 - Released on Canon website

I am having the same problem as everyone here. The following trick helps temporarily:


- Open Terminal
- enter "sudo launchctl stop com.parallels.desktop.launchdaemon" without the quotes
- enter your password
- Print (or restart the print queue)

If you want to use Parallels afterwards, either restart the computer or type

"sudo launchctl start com.parallels.desktop.launchdaemon"

in Terminal

Works for me for now, still waiting for 10.6.2

stopping com.parallels.desktop.launchdaemon doesn't help in my case 😟 I was exactly looking for that kind of workaround but tried to kill all processes via Apples Activity Monitor also with no success.

Same problem to me - I always only saw the scanner and I have also Parallels on my system.

- I removed all printers
- entered the command in the shell from oleolo
- hit the "+" button in the printer setup
- scanner came up AND 10 sec later the printer - YEAH
- now everything is working fine for me

Thanks to oleolo for the trick!

Hi everybody,

I've been through the exact same problem.

By the way I've finally solved it. On my MB, I'm also using Fusion 3 with two virtual machines. I didn't uninstall Fusion.

My printer MX850 didn't show neither in the Canon IJ Network Tool nor in the Add Printer menu is System Preferences.

Here's how I got my MX850 to install:
- I opened System preferences > Printers
- In the printers list, I right clicked and selected 'Reinit system' which deleted every installed printer
- I clicked on the + to add my MX850
- I waited 8 seconds and the MX850 Bonjour scanner showed, then appeared the MX850 printer ijnetwork
- I selected the MX850 printer ijnetwork and it installed automatically 😉

(Note that I had already updated the CUPS printer drivers because I'm under 10.6)

Let me know of how it goes for you, I'll tell you if my solution keeps working across time

romaric17's solution may resolve problems with Fusion & MX850, but it isn't a workaround for my problem with Parallels and MX850 printers. Are folks still assuming that 10.6.2 will resolve this?

At first sight the 10.6.2 update did not fix the problem. I have to check this later (deinstall printer, reinstall) to be sure.

Are you using Parallels 5? I thought I saw a posting from someone who said that v5 resolved this network issue.

Hi,

i was facing the same problems with Parallels 4 and the mx850 Printer.
Now i´m using the Trial of Parallels 5 and after resetting the Printersystem and clicken on + my Mac first found the bonjour scanner and FINALLY the printer.
i´m using the latest CUPS drivers. Which i didn´t reinstall before trying to add the printer.

Finally I can print!!!!

Hope this will work for you all too!

I recently switched from PC to Mac. My new iMac seems to be working fine connected over USB to my MX850. However, I can't find any way to set up default preferences for the printer. I have to enable duplex printing every time I print. Is there some other way to do this?

Thanks

Thanks Ken. I'll give it a look. /David

Hi,

Yesterday I received my Parallels 5.0 upgrade and after installation my problems were gone. My MX850 just prints via network as expected.

Thus Parallels 4.0 is causing problems when used with MacOS 10.6.x.

Fortunately I was within the extended grace period and had to pay "only" $10 for the upgrade. I would have expected Parallels to solve the problem for v4.x

Thank you! The terminal command to stop Parallels launch daemon worked for me under 10.6.2 with a Canon MP980. Once I stopped that process, the printer appeared in the Add Printer dialog a few seconds later (and this after 30 minutes on with tech support and multiple re-installations). Hopefully they can add this to their database soon as it appears many of us have called in with this same issue.

I am new to this Forum!!! I hope this is the best thread for this question. I have just gotten a laptop with OSX 10.5.6 and have been trying to get my MX850 to print and have been unsuccessful. The Canon website lists both the latest CUPS driver and the V7.1.1 drivera as both being useful for 10.5. Which one should I use?

I first tried installing the CUPS driver using the downloads from the Canon website. That didn't work so I tried installing the V7.1.1 driver and that didn't work. What should I use? Do I have to remove or undo my "double" driver installation? I am new to the world of Macs so please be gentle with me!!! Any help is greatly appreciated!.....I see from browsing these forums that you're a help community.

Hi Crispell,

Just use the included CD for installation. For MacOS 10.5.x they work just fine. Afterwards you may update the drivers if you need to. You need the canon network scan tool to find the printer via network. Only the drivers won't work as Canon MX850 does not support "normal" network connections but a special solution from Canon which only works for Win & Mac.
