HP Printer Driver 1.1 released

My networked LaserJets (3 different models) worked fine before installing this update, then started giving me the:

/Library/Printers/hp/filter/hpPostProcessing.bundle/Contents/MacOS/hpPostProces sing failed

error (not the crash -- it just barfs and I can't print anything).

Re-downloading and re-installing drivers for one of the printers (LaserJet M5035x) straight from HP appears to have solved the issue. At least on the two LaserJets that worked up until last week.

I have since learned that the Laserjet 1022 was not included in the HP Printer Driver 1.1 Update from Apple. So, I am not 100% sure why your printer kept on working and mine stopped/switched to GutenPrint driver.

See list of printers included in HP Printer Driver 1.1 Update:

Big deal, I couldn't print out of Photoshop CS3 before the update, and still can't print out of Photoshop CS3 after I ran the update.

Saving as JPEG and Preview still works, tho...

It seems that this issue is tied to presets. You can try this as a workaround:

"From print dialog box, delete any custom pre-sets that may have existed before driver update. After driver update, user can recreate custom pre-sets and all should be good."

Recreating the presets solved the problem for me too. Thank you gavinmster

Regarding hpPostprocessing errors, there may be a conflict with older custom presets.

From the print dialog box, if you have custom presets you've created in Tiger prior to Leopard update, there may be an issue/conflict with the custom presets. Just delete the preset and then recreate/save a new custom preset (e.g. duplex on, 2up, etc) and you should be OK.

I was working on a co-worker's HP Laserjet 2420 (print jobs were stopping). He ended up removing the Adobe plug-in for Safari which solved the problem.

Hmmmm

Since installing the HP update in software installer my Multifunction printer can no longer scan!!!!!!!!!!

Every time I try to scan something I get an error 'Sorry scanner cannot be initialised' error communicating with printer.

Nothing wrong with printer as my wife's laptop has not been upgraded and this scans fine on it.

Bugger!!!!!!!!!!!!!!!!!!!

yup, here too. HP drivers update v1.1 via Software Update hosed my perfectly fine HP Laserjet 2420:

Library/Printers/hp/filter/hpPostProcessing.bundle/Contents/MacOS/hpPostProcessi ng failed

deleting the presets solved the problem.

This was my problem. I deleted my custom presets, and everything started working perfectly. Thank you, thank you!

Just to add another 'me too', alas printing from filemaker will not work at all, as the presets are set within the filemaker script.

Well done apple!!

Downloading driver from HP to hopefully solve the problem.

Just to concur, download the drivers from HP, install, re-start, remove and add the printer, and hey presto.

I guess I wouldn't be so quick to blame Apple for this. I believe the updates came from HP and were distributed by Apple using their auto-update feature. I can't imagine Apple writing drivers for HP printers. Same with the problem with Filemaker. It could just as easily be HP's or Filemaker's fault for not following the rules.

I would agree, if not for 2 things.

1. The HP software on the HP site is still the old version.
2. Nothing has changed within filemaker.

But the rules that Apple sets for developers also include rules that will keep software from developing conflicts as they implement new things they are planning in the future. And as to HP still offering only the older drivers, it looks to me that they therefore provided them to Apple before extensive testing that they planned to do before releasing them on their own site.
