One of the largest complaints heard from Mac OS X Public Beta users has been the lack of printing support. Obviously the paper-less office is not quite a reality yet, students have papers to print, SOHO users have invoices, and some people still print out email. After trolling through several Mac OS X forums I've stumbled upon a hack that can actually get printing to function under Mac OS X. At this time I'm unsure of what printers it works with. It seems to work on USB HP printers that are in the 8xx series and the 9xx series, but support varies. On my Deskjet 812c it works perfectly except for the lack of color. Other people have found it prints in limited color very slowly, some can't even get it to print accurately, so try this hack at your own risk. If you'd like to send in your results with a specific printer model, please email them to .

Here are the instructions to enable printing under Mac OS X (special thanks to Andrew Potter for letting me gank them):

• First, become an online member of the Apple Developer Connection. This is free and can be done in just a few minutes at
• Once you are logged into the ADC website download the Tioga SDK file
• After this file is downloaded, rename it to tiogasdk.tgz
• Move the tiogasdk.tgz file into the Applications folder
• Open the Terminal application
• Type su
• Enter your password at the prompt
• Type cd /
• Type cp /Applications/tiogasdk.tgz /tmp
• Type gnutar xzvf /tmp/tiogasdk.tgz

That's it! Now when trying to print from a Cocoa or Carbon application you should be able to select a printer in the Print Center. Please note that you may not see your exact model in there, for instance the HP 810 was listed for me, but I have an 812c, selecting th 810 worked perfectly, though. Good luck, and happy printing!
