Manufacturer Part #: AS-451P
Either switch automatically or manually to share one parallel device (such as a parallel printer) between 4 PCs.
The switch features a manual switch on the side to turn off the connection to any combination or all of the computers. 4 DB-25 parallel ports (aka centronics A) link to your PCs using a standard DB-25 parallel cable. Your parallel device links to the fifth port. The share switch will automatically switch from PC to PC unless one port is manually turned off.
