Introduction
The TDP4*H printers utilize a Plug-In Interface Module for maximum printer configuration flexibility. This section
presents the interface specifications for the TDP4*H printers. These specifications include detailed information on
how to properly interface your printer with your host system.
The following information is presented in this section:
• Interface Types
• Using the Receive Buffer
• IEEE1284 Parallel Interface
• Universal Serial Bus (USB) Interface
• Local Area Network (LAN) Interface
• RS232C Serial Interface
• Bi-Comm Communications Protocol
• Status Response
Interface Types
The parallel interface for the TDP4*H printer series is a high speed, bi-directional interface that conforms to
the IEEE1284 specification (ECP series mode on some computers). The interface is also compatible with the
older Centronics parallel interface standard. If it does not detect the correct IEEE1284 signals in the interface
connection, it will automatically operate in the standard Centronics mode which is much slower. To use the
IEEE1284 parallel interface to its fullest capability requires that the host also have an IEEE1284 compatible
interface and that the two be connected with a cable that meets the IEEE1284 specification. If either of these
two are not present, the data rate is severely compromised.
In order to provide flexibility in communicating with a variety of host computer systems all ìeî printers use a
Plug-In Interface Module. The IEEE1284 Interface module is shipped with the printer unless another interface
type is specified at the time of the order. The other interfaces available are a high speed (to 57.6K bps) serial
interface, an Ethernet interface or an optional Universal Serial Bus (USB) interface.
The Parallel interface will probably be the most useful in communicating with IBM PCs and compatibles. The
RS232C Serial interface allows connectivity to a number of other hosts. The USB interface allows the printer to
be connected to a computer that supports peripherals attached to a USB bus. Up to 127 peripherals can be
connected to a single USB port. The interfaces available are a high speed (to 57.6K bps) serial interface, an
Ethernet interface or an optional Universal Serial Bus (USB) interface.
