Ports

 

A port is a name of the interface you printer is connected to.

Normally it is one of the following:

  • LPTx ( LPT1, LPT2, ... )

  • COMx ( COM1, COM2, ... )

The most common interface for printers is the parallel interface (LPTx). the parallel cable has 25 pin male connector on one end and a 36 pin special connector on the other end. Most of the PCs have only one parallel connector named LPT1. This is the default used in TextPrinter.

The serial interface (COMx) is a bit different in technology from the parallel. It has a different cable with 9 pins. From the point of view of the developer, the serial interface is similar to the parallel.

There are some printers there with other interfaces, for example a USB interface. Those printers have not been tested with TextPrinter but may work if you specify the correct port or if you use a simulated parallel port. If you have trouble making such a printer work with TextPrinter please contact support.
