Problems with EFI Fiery Drivers - Slow Performance

[tnielsen]

We have Canon IR-AVD C7565 Printers attached to EFI RIP GX500. We have been seeing very slow print window load times when trying to print from any app.

We narrowed the issue down to the driver, however I was wondering if anyone else uses/manages these EFI Fiery Rips. Maybe you don't use the EFI driver at all, if that is the case, which do you use?

For anyone that may come across this post. You can significantly improve printer performance by disabling the EFI fiery print PLUGIN. A simple one liner does it:

defaults write /Library/Printers/Canon/PS3/PDEs/EF565447/EF565447 (FF).plugin/Contents/Info.plist PMSandboxCompatiblePDEs bool=false

This does not allow the plugin to load for any sandboxed applications, which is just about every app nowadays. You will still get all your printer options through a dropdown menu. After making this change, printing was instant.

Understand that this is just ONE plugin for ONE printer. You could do this for any plug, however. To identify which plugin your printer is using, open the associated .PPD file and scroll to the bottom. It tells you there. Find the plugin and show contents. find the info.plist and make the changes as above.

Highly suggested.
