About printing with a USB-to-parallel cable
If you use a USB-to-parallel cable, these issues may occur: The print queue may stop, pages may not print completely, a "communications" alert may appear, or no printer driver may be found when adding a printer, even if the printer's software is installed.
The printer drivers included with OS X are designed to work with many printers via a USB or network connection. However, Apple does not test the drivers with USB-to-parallel cables, converters, or adapters.
Although you may be able to print successfully when using a USB-to-parallel cable or adapter, you should use a USB cable or network connection (Ethernet or wireless) with your printer whenever possible. Otherwise, contact the manufacturer of your printer, cable, or adapter for compatibility information and assistance.
A USB-to-parallel cable can be identified by the 25-pin or 36-pin connector on the end of the cable that connects to the printer. A USB cable will have a USB type B connector (4 pins) on the end that connects to the printer.
In Mac OS X v10.2.x, using such a cable could cause Print Center to unexpectedly quit.
