Appendix D
Control Code Comparison
The first part of this appendix consists of a chart of the commands
used on Epson printers. It shows similarities and differences between
the MX III, the FX, and the RX. Unless otherwise specified, the FX
column applies to both the FX-80 and the FX-100, and the RX column
applies to both the
RX-80
and the
RX-100.
In the second part of this chapter, we summarize the differences in
software and then cover variations in hardware features. The com-
mands, both in the chart and in the prose summary, are arranged in
ASCII order.
