Access serial port printer over Network

Olga Weis

Most industrial printers connect to a computer via serial port. One end of a serial printer cable is attached to a serial port on a computer, while the other goes to the adapter card on a printer. If you need such printers regularly, you would know that more often than not we need to access them remotely. The reasons might vary – your printer may be way too bulky to be moved around or it might not be feasible to run a cable for a long distance, etc. Serial to Ethernet Connector is special software that enables reaching a serial printer remotely over network.

The way it works is pretty simple – it emulates a serial port on a local computer, and via virtual null modem connection this virtual port mirrors the real hardware port on a remote computer.

There are various scenarios in which Serial to Ethernet Connector can be used – let us have a closer look at them.

Remote serial printer usage scenarios

Scenario 1. There is one COM port printer and it needs to be shared among several network users.

Download and install Serial to Ethernet Connector on a computer to which the printer is attached (server) and computers that need to access it remotely (clients). Launch the application on the server and ‘Share’ RS232 printer, now client machines can ‘Connect’ to it over network and use it as if it were attached to their local machines.

Share serial printer between several PC

Scenario 2. RS232 printer is connected to a serial port on your local computer, and you need to provide control over it to an application on a remote target machine.

Install Serial to Ethernet Connector on both computers. On the target machine the software will emulate a serial port through which the application can communicate to the real serial port on your local computer. The underlay protocol used is Telnet, this allows the app control settings of the remote port.

Manage industrial printer remotely

Scenario 3. You have RS232 industrial printer connected to your PC, and the application that needs to interact with it is not compatible with the OS on your computer.

Install Serial to Ethernet Connector and run a guest OS that supports your application. Now on the host OS you can share the port to which your printer is attached – your host OS turns into a server. Now from the guest OS – it acts as a client here – you can connect to the shared port. Specify the IP address of the server (or network name) and TCP port. All data will be redirected to the application and can be processed by it.

That’s pretty much about it – these are the main scenarios when Serial to Ethernet Connector can be used for sharing a serial printer over network.
