Solution
The interface may not be configured
correctly. If you use a serial interface,
make sure that both the computer and
printer are set to use the same number of
data bits per word and that they both
use the same parity, baud rate, and
number of stop bits.
You can also use the data dump mode to
check the data being sent from the
computer, as described later in this
chapter.
The printer mechanism may be faulty.
Try running a test print as described in
Chapter 1. If it is not printed correctly,
contact your Epson dealer for assistance.
The condensed mode may be selected. If
your application program can send
control codes, cancel the condensed
mode by sending the DC2 code to the
printer. Also, you can set the SelecType
condensed mode menu to off, as
described in Chapter 2 to change
SelecType settings.
