My problem with Lightroom(64bit) crashing whenever I tried to print to my Canon iPF5100 still exists. Up 'til now I have worked around it by switching LR to 32bit whenever I need to use the 5100.
What is pushing me to the edge now though is that the just released 5100 64bit print plugin for PS CS5 is causing PS to crash!
I assume the same cause (whatever it is) lies at the bottom of it all.
On 10.6.5 / LR 3.3 / PS 12.0.2
The printer firmware and driver and print plugin are all the latest versions (just downloaded & installed – again – to make sure).
Canon support (not yet contacted with the PS problem) had me do the following 11 months ago to try to fix the LR crashing, with no result. I've just gone through it again, plus using Spotlight to track down & trash any hint of old 32bit 5100 driver remnants, pref files etc, before installing the 64bit driver.
"1. Remove Printer Queue
2. Run Reset Printing System (right click on printer list and reset)
3. Run Repair Disk Permissions (Utilities folder>Disk Utility)
4. Trash Library>Printers>Canon folder if possible if no other Canon printers are installed. (make sure of this location, NOT users folder>library>printers)
5. Otherwise, Trash Library>Printers>Canon>GARO
6. If not all files are removed and state in use, then kill process using Activity Monitor, then Trash (Utilities folder>Activity Monitor)
7. Empty Trash
8. Run Repair Disk Permissions again
9. Restart
10. Re-install (via a static IP Address, not Bonjour)"
When troubleshooting this earlier I even reinstalled the OS before retrying everything, to no avail.
If anyone can offer a suggestion or make sense the crash logs I'd be MOST grateful.
