Change Printer Connection
By: Sergio - 9/19/2014

One topic I want to talk about is swappable interface cards. There are a few manufacturers that offer interchangeable connections on printers. These are commonly known as interface cards, or interface modules. Interface cards are commonly found through Epson, Star Micronics, Samsung, POS-X and a few others. Availability on these sometimes varies between different makes and models.

These are used when migrating to newer systems that have different port options than what your printer is compatible with. For example, if you have an Epson printer with a Serial connection and you purchase a new computer that does not have any serial ports, you would then purchase a USB interface card to make your printer compatible. This is the simplest and most cost effective solution.

The installation is fairly simple, on the back of the printer there should be one or two screws you remove. Then pull out the connection board and replace it with a new one and screw it back it. Some pin adjustment and configuration may be required for this, however it generally is pretty straight forward. Next step is to acquire the correct cable for the new connection and connect.

This solution is most common when needing to share the printer with more computers on the same network. You would swap the current interface for it out for an Ethernet (network) connection. If there are any questions or to find the correct interface card, give us a call.
