EPOS Deviations

There are several important differences between the Series 90PLUS and Epson printers. The closest Epson
models to the Series 90PLUS Printer are the TM370 or TM375. An application that takes full advantage of
the Epson printer will require some modification to use a Series 90PLUS Printer. The biggest differences
between the TM370 and Series 90PLUS Printers can be grouped into three areas.
The first is mechanical. The Series 90PLUS Printer has a larger print zone than the TM370 printer, and the
top and bottom form limits are slightly different. In addition, the receipt paper is wider in the Series
90PLUS Printer, and the larger print zones allow more characters to be printed.
The second is page mode. The Series 90PLUS Printer does not implement page mode the same way as the
TM370 printer. If the application uses page mode, it may have to be changed. The biggest difference
between the TM370 and Series 90PLUS Printer is that the Series 90PLUS Printer only buffers print
information in 90 and 270 rotated print. In addition, the Series 90PLUS Printer does not allow the rotation
mode to be switched during format development.
The third major difference is that the Series 90PLUS Printer does not implement real-time status responses
the way the TM370 printer does. Several bit definitions are slightly different.
