Thanks to a tip from a MacInTouch reader, my PowerBook, running Mac OS X Tiger 10.4.1, is successfully printing to my HP OfficeJet d145 again. It was quite simple. First, in the Hewlett-Packard folder that would be installed in your Applications folder, run the HP Uninstaller application. When it's done, restart your Mac. Next, make sure you have the latest HP driver software for your OfficeJet, in my case the d145 on Mac OS X. After mounting the disk image, quit all other running applications. Or just run the HP All-in-One Installer, as it is going to ask to do this for you. Let the installer run as normal, and run through the Setup Assistant stuff at the end. The Setup Assistant saw my OfficeJet sitting on its assigned IP on the internal network. After that was done, I launched TextEdit, typed in a line, made several copies of said line, and sent it to the printer. Voila! Happy days are here again in the Phisch Bowl™. Your mileage may vary, but this is what worked for me. I have not tested any other functions, such as faxing or scanning, from the HP Director software, since I didn't really use those functions before.
