If you have a printer queue window open when printing from a Classic application, the print job may not print or appear in the printer's queue.
Make sure the printer's queue window is not open and the printer's icon is not on the Dock with a triangle by it (indicating it is open).
After closing the printer's queue window or quitting the printer queue application shown on the Dock, try printing from Classic again.
Mac OS X 10.4 or later allows Classic applications to print to printers that were added in Mac OS X without installing printer drivers in Classic or selecting the printer in Chooser.
