Hello everyone! I've been waiting to register on LL for a very long time now, it looks like registration is open again for new members. I have posted this on GetDPI's forum and wanted to post this here too. Here's a quick solution to get the CS3 IPF5100 printer plug-in to work Photoshop CS4.
Open up the IPF5100/6100 CS3 Print Plug-In, instead of allowing the installer to automatically install into Photoshop CS3's directory, click on Choose Destination. The installer will then close all applications, so make sure that you've saved your tabs in Firefox, Photoshop images, etc. A destination finder will pop up to choose the target location, go to Applications/Adobe Photoshop CS4/Plug-ins and click on the Choose button. After that, the installation will proceed just like normal and will pop up in the Export tab under the File menu in Photoshop CS4.
If you have any profiles that you would like to transfer over to Photoshop CS4-
Macintosh HD/Library/Application Support/Adobe/Color/Profiles.
ColorSync Folder Path-
Macintosh HD/Library/ColorSync/Profiles.
Make sure you run Disk Utility in Applications/Utilities to repair your permissions on your OS X partition. Then you're done.
Hope this helps,
Andrew
