Updated to 10.6.8, now I can't print

To those using Konica's. Well it worked for the Macs, but caused the Windows 7 machines to show the printer offline. Turn it back on and ran the vcboy.com fix and it seems to be working after I reset my power management, some reason my backlight turned off on my Macbook Pro after logging in.

According to Apple Support there is no problem, the drivers need to be rewritten. Welcome to the future, watch out for Lion this is only the beginning.

I also have been affected by this (non)print bug since I installed 10.6.8 a couple of weeks ago. The affected printer is an HP6940 attached via USB. My symptoms more or less matched those here with one exception; in my limited experimentation I found that I could get Preview to print without any issue. Other programs would print a few lines and then hang. Acrobat Reader, in particular, was affected by this. I had also found that the HP printer utility could print a full page w/o any issues so, according to the HP Utility, the issue was not with the printer itself or being able to communicate with it, but most likely a driver or other software issue. This seemed consistent with the fixes described in this thread.

Anyway, I figured that my first attempt to remedy the problem would be to implement the PPD edit outlined here as that appeared to be the simplest solution. Just for kicks, I tried one more time to print a page from Acrobat Reader. It worked. Huh? I opened up the PPD file and, to my surprise, there was already a line in the file that had the necessary setting (*cupsSNMPSupplies: False).

Perplexed, I backed out of the file with no changes and I noticed that the PPD file datestamp info was basically the time I tried the Acrobat Reader print experiment and that there was a ".O" version of the same PPD file in the directory. I tried using "diff" from terminal on the two versions but it did not detect any so I'm not sure why the ".O" version is there.

Has anyone else had the problem magically go away like this? I'm wondering if the HP driver was able to update itself on the fly, replacing the PPD file, and work around the problem.

In the end, the good news is that I'm apparently able to print fully again. On the flip side, I have no idea why.

Hope this helps any other HP printer users,

ABG

Thank you, as I have the exact same problem but related to the FX Docucentre II 4000 printer.

My problem is, can someone spell out where on my HD the directory for the ipp and the lpd files are stored please?

My spot light does not see any of these folder names:

/usr/libexec/cups/backend

or files called:

socket

dnssd

lpd

ipp

If someone would be patient enough to assist a novice like me that would be appreciated. I can then locate them in my Time Machine Back ups to restore the older lpd files.

Hi Truk1-

If you read the entire thread (lengthy, but worth it) you'll find explicit instructions. I believe the really good summary I followed is on page 18.

Here's a synopsis;

The folder you need to go to is a "hidden" folder. If you're unfamiliar with Terminal, use the Finder "Go To" command (shift-command-G) and enter the directory, e.g. "/usr/libexec/cups/backend". You'll then see a directory with the programs that need to be replaced (or, in /usr/libexec/cups/backend you will find the PPD file that needs to be edited).

Good luck.

Alan,

Excellent help; thank you. And yes, it worked really well. Phew!

For fellow novices like me, this link also offers an easy to follow instruction; thank goodness for TimeMachine:

PS. as a side note, is there a way to optionally make spotlight 'see/find' hidden files and folders?

this printing problem with 10.6.8 has been hitting most of mac users and i heard that there is repair patch of a dmg file for this problem ? is it available online ? i hope this for free downloads otherwise people might think that this is a simple scam to sell the repair software

snbriones - see http://electro-music.com/forum/viewtopic.php?t=48419

This is the patch I submitted to Xerox in Norway. All the patches that have been flowing around are exactly the same. This won´t actually repair anything, but will downgrade the cups printing system to something close to 10.6.7 and this will restore network printing. I have also posted a restore app that will restore OS X 10.6.8 CUPS if that is called for at a later time.

The .ppd hack worked for me.

Xerox DocuColor 252 w/built in Fiery network printer.

My HP LaserJet 1022 worked perfectly fine via network with Airport Extreme until I did the update. I couldn't print unless I hooked it up directly to my MBP via USB, which was really annoying. Looked online for HOURS for a solution. Found a post here by vcboy and it worked!!! Such an easy fix! Wish I had found this sooner so I didn't have to waste so much time & effort on this problem.

Thanks vcboy!!!

Lykeios, thank you so much. Your patch worked immediately. You are awesome.

One thing for everyone to keep in mind -- while Apple might have fixed the lpd file before shipping Lion, don't be surprised if it's broken and you have to scramble to fix printing after upgrading to 10.7. Put this high on your checklist of things to look for after Lion.

I can report that our networked Sharp MX-5001N also goes into "permanent pause" mode in 10.6.8. (Yes: latest drivers from Sharp installed; etc.)

Our other networked printer, an HP LaserJet P2055dn works fine.

Am I now waiting for Sharp to update or Apple?

Use the fix that is in the 1:06 am post from today. Worked for me on my printers that would not print while others would.

Hi,

Just upgrade to Lion in my Macbook Pro 15 2010 and Mac mini Server 2010. Both are printing normally.

Not very user friendly or considerate they haven't corrected 10.6.8.

On another issue re Lion, I'm now having trouble connecting to my ReadyNas Pro NAS, namely, I lost Time Machine capability....
