Undocumented Epson Commands

There are a number of undocumented commands in Epson printers. Where TransAct is aware of these commands,
they have been duplicated in the POSjet
make it more compatible with the TM-U325. TransAct can not guarantee that we have identified all of these
commands. If your application does not function correctly, it is possible that you are using some of these
commands.

Real-time Status

®
The POSjet 1500 Printer is available in serial and parallel versions. Epson supports parallel operation but does it
through a parallel to serial interface. Consequently, the response times for the POSjet
®
faster. The POSjet 1500 Printer implements the IEEE 1284 nibble-mode standard. If an application requires real-
time status from the printer, the IEEE 1284 bi-directional protocol must be used. The POSjet
support byte mode. If the POSjet
extension and the default should be nibble mode.
®
The POSjet 1500 Printer supports the EPOS real-time status commands [DLE] [ENQ] and [DLE] [EOT] and are
preprocessed by the printer. The printer supports all the response bit fields as defined by the TM-U325D Printer.
See the descriptions below. The POSjet
does not respond to [DLE] [ENQ] or [DLE] [EOT] commands that happen to be embedded in graphics or other
commands. (Refer to the buffer and preprocessor descriptions in later sections.)
