Introduction

AF-142 and AF-241, ParaHubs, are automatic and first-come-first-served data switches. They scan for print job requests from both computers and send data to the printer. When one computer is printing, the other computer can not send print job until the current one is finished. The File Transfer feature enables you to access the other computer directly through the ParaHub and requires no special cables. Besides, the AF-142 can operate as a 1-to-2 selector enabling you to connect the LPT port to two parallel devices.
