Check that the printer has an ample supply of media and, where
applicable, of thermal transfer ribbon. Refer to the EasyCoder E4
User's Guide for loading commands.
Check that the printhead is lowered. Turn on the mains switch,
which is fi tted on the printer's rear plate, and check that the
Power LED comes on.
Check that you have a working two-way serial communication
by sending a simple command from the host to the printer. On
the host, type:
? VERSION$ ↵
Provided you have serial two-way communication, the printer
should respond by immediately returning the version of the
installed Intermec Direct Protocol fi rmware to the screen of the
host, for example:
V2.10
Ok
This indicates that the communication is working both ways.
If the communication does not work, switch off the printer and
check the connection cable. Also check if the communication
setup in the host corresponds to the printer's setup, check the
verbosity level, and check if the connection is made between the
correct ports. Then try the communication test again using the
Dump Mode.
Once you know that the communication is working, you may go
on and send a line of text to make sure that characters transmitted
from the terminal are interpreted as expected by the printer's
fi rmware:
