EPOS Codes

This section lists the EPOS codes that are supported by the Series 150 Printer. Ithaca Peripherals has no control over how Epson extends or changes these control codes. Ithaca Peripherals makes no guarantees as to the operation of its printer when it replaces an Epson printer. The EPOS emulation is intended to make it as easy as possible to replace an Epson printer with an Ithaca Series 150 Printer.

The following section lists the EPOS commands that are processed. They are as close as possible to Epson printers. The user must remember that the Series 150 Printer is not designed as a drop-in replacement for an Epson printer. The Series 150 Printer is designed to bring new and unique features and functionalities to a POS receipt/validation printer.

Real-time Status

The Series 150 Printer is available in serial and parallel versions. When Epson supports parallel operation, the company redefines some of the standard IEEE 1284 interface signals to be special status lines. The Series 150 Printer does not alter the IEEE 1284 standard. If an application requires real-time status from the printer, the IEEE 1284 bidirectional protocol must be used.

The Series 150 Printer supports real-time status. The EPOS real-time status commands [DLE] [ENQ] and [DLE] [EOT] are processed by the printer. The printer, however, does not support all the response bit fields. See the descriptions below.
