Updated to 10.6.8, now I can't print

It is so frustrating when an update actually has a detromental effect. Ahrrr

This solution worked for my system (Xerox Docucolor 242). I removed the printer, replaced the 4 backend folder files with files from another Mac in the office that had not been updated, repaired disk permissions and restarted. Back to printing.

You would think someone would have tested this update with Xerox printers. Quality control must either be in a big hurry or they're just not on the ball.

Thanks all for helpful hints on here... finally sorted it using IP printing. However this is not a long term solution. Apple, please sort this asap!!

Thanks, everyone. Replaced ldp file and I'm making money again. You guys saved me.

Lykeios I hope you can help me out. I do run the patch you suggested but now I dont get Paused, I just get Conecction Atemps, but from all the Printers even the ones that do work, hope you can help me out. I just cant find the paths you mention

Is like you were using some kind of Windows Explorer path bar

I dont know hopw to do that on my iMac

Hope you can help me fx it with out reinstall OSX and TimeMachine

Lykeios, nice script (although I would of course suggest anyone trying it verify it's contents for their own). Replaces the four suggested files, and I can confirm it resolved my particular issue (Bonjour queue to Xerox Fiery).

Lykeios: Thanks so much. Ran the script and it solved the problem. Don't know if it's necessary, but I first reset the printing system, then applied the script, reset the printing system again, restarted the Mac and then added the printer back in. Worked like a charm. Incidentally, I had brought in the dnssd file from a mac at home that I hadn't updated because the log indicated that was the problematic file, but it didn't help, so obviously one of the other files was also problematic. I am using Bonjour with a Toshiba e-studio 450.

I'm in the same boat, one of my computers has been fixed, but now on another one I get errors that all printers won't work even the one's that would before. Is there a way to reset the whole backend folder?

Computer that fixed is an imac running 10.6.8, computer that won't fix is a mac mini running 10.6.8.

After installing 10.6.8 on my 2011 MacBook Pro, I, too, had the printing problem - my Canon PIXMA MP990 would time out after each print. I print to it wirelessly. I was uncomfortable replacing a file in a hidden System folder, so I tried the other suggestion somewhere on this posting. I went to the Print & Fax pref pane and CTRL-clicked on the printer. I then selected Reset Printing System. I then had to reload the printer and reset its paper handling and ink preferences because the original ones had been deleted. However, now my printing is running is it did before the 10.6.8 update. All this is using Apple's own method of fixing, rather than applying a kluge.

Well an employee here replaced the whole backend folder rather than the four files within discusssed earlier, would it be possible to replace the whole backend folder from a different computer that is still on 10.6.7, or is there a way to reset it back to normal somehow? Thanks.

Im sorry, but I never neede to go on the system files before since I switch to Mac 9 years ago.

I run the Script some of the users kindly upload, but It didnt work in my case. Have to Restore from System Disk and Time Machine, but Im still on 10.6.8 problem, Paused.

I see some other users of Docucolor 242/252/260 have restore from Backups earlier of June 25. I want to try that fix, but honestly I dont see files the way you do, I dont know if its because my system is in Spanish.

Im attaching a view of my folders I hope someone can tell me how to do it.

I dont see things like /usr/libexec/cups/backend

Yes, you can indeed copy the lot from a machine running 10.6.7. However, if you take a look in the backend folder not all the files located in the backend folder are real files.. some are aliases. I wouldn´t mess with the aliases. I guess most have seen my fix suggestion posted at the Xerox and Fiery forums.

A point to make is that I´m addressing the bug concerning network printing.. not to a locally connected printer ( we don´t have any here ). BTW, the links in the backend folder .. if the files they points to are messed up then the real files have to be replaced to and the links refreshed to the new files.

I imagine many will have aliases to the "canonijnetwork", "HP-fax" and the "fax" files .. all of these are located outside of the backend folder. I repeat, don´t mess with these aliases. You might discover that some aliases are named differently than what the files they point to are. Example: HP-fax links to a file named HPFaxBackend inside the library/printers/hp hierarchy.

Copying by means of ARD is quick and safe.. as long as you know what you copy, to where and why.. :-)

You could of course use Apple´s installer builder app in order to build the fix into an actual installer app but for most workplaces using ARD is much faster. I imagine many will have aliases to the "canonijnetwork", "HP-fax" and the "fax" files located outside of the backend folder.
