| Panasonic KX-P2123 serial printing to powerbook? |

All,
What type of RS-232 interface do I need to have on my KX-P2123 to print from a powerbook 5300?
There are 2 interface types I can get for my Panasonic printer. Current loop and non-current loop interface boards.
Does the Mac require a "current" on the RS-232 for printing?

You want the KX-PS11 RS-232C serial interface board. (Not current loop)
Current loop interfaces use current instead of voltage for signalling and are advantageous for very long cable runs where voltage drop would be an issue. They are not directly compatible with ordinary computer serial ports- a current to voltage translator interface is required.
