Intermec EasyCoder 301 Direct Protocol 2.0 – Programmer's Guide Ed. 3
Chapter 2 Getting Started
Check that the printer has an ample supply of paper or other receiv-
ing material and, where applicable, of thermal transfer ribbon. Re-
fer to the EasyCoder 301 User's Guide or Installation and Opera-
tion Manual for loading commands.
Check that the printhead is lowered. Turn on the mains switch, which
is fitted 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 Inter-
mec Direct Protocol firmware to the screen of the host, e.g.:
V2.00
Ok
This indicates that the communication is working both ways.
If the communication does not work, turn 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 software:
PP 10, 10

FT "Swiss 721 BT"
