When you install printer drivers on a machine running OS X, you must also install the OS 9 driver(s) for your printer(s) into the Classic environment on the machine. Since Helix takes you into Classic, it needs to find the appropriate print drivers there in order to print. Locate your CD-ROM that came with your printer and perform the OS 9 driver installation recommended by the manufacturer and your printing problem should be solved.

Beginning with OS X 10.4, Apple has provided a way to print to printers through the OS X printer drivers. To do this, first select "LaserWriter 8" in the Classic Chooser (regardless of whether you have laser printers or not). Now, when you print, the print dialog should show a popup menu at the top listing every printer installed for your OS X user. Printing this way uses the LaserWriter 8's capability of creating a Postscript (.ps) file to generate an "image" of the page that OS X printers can process.

Helix RADE, Engine, Client, and the utilities run fine in Classic Mode under OS X. However, the Classic Helix Server (5.3.2 and earlier) is not compatible with OS X's Classic Mode. Running Server in Classic mode can result in irreparable collection damage.

Users who need to purchase an OS X Mac for their Helix Server should also upgrade to Helix 6.0 or later.
