Communication Overview

In order for a receipt to be printed, a program must be in place that translates the data from the host system into a language that the printer can understand. This program must tell the printer exactly how to print each character. This chapter describes how to create such a program or modify an existing one.

Interfaces

In order for the printer to communicate with the host, a communication link must be set up. The 7193 supports the following three communication interfaces:

∙RS-232C Interface

∙Parallel Interface

Each of these has a protocol associated with it that the host must understand and adhere to. Only when the interface parameters are matched and the proper protocol is used will the host and the printer be able to communicate. See the respective sections in this chapter for a description of the protocol associated with each type of interface.

Sending Commands

Once the communication link is established, commands can be sent to the printer. This section describes how to send commands to the printer using DOS and BASIC. This section does not take into account the necessary protocol, but is meant as a general introduction to how the printer functions.
