Intermec EasyCoder E4 LinerLess – Installation & Operation Ed. 1
The EasyCoder E4 LinerLess can use the Intermec Direct Protocol
programming language as an alternative to the Windows driver. It
is an easy-to-use printer protocol that has been developed for use
with the computer-controlled direct thermal and thermal transfer
printers manufactured by Intermec.
Intermec Direct Protocol can be used to send instructions to the
printer in two ways:
• To create label layouts consisting of fields with fixed or variable
information. A layout can then be selected and provided with
variable input from the host computer in the form of a simple
string of data.
• To send input data and formatting instructions as a continuous
string of data directly from the host computer.
The EasyCoder E4 LinerLess is designed to operate with anything
from an unintelligent terminal to a mainframe computer system.
The host computer only needs to be able to transmit characters in
ASCII format. It is preferable to connect the printer to the host via
the serial RS 232 port, which will provide two-way communication
and enable printer errors to be returned.
• If the printer is to be controlled via the Windows Terminal
application, connect via the serial RS 232 port. You can type
commands directly into the Terminal, or compose them in
Notepad or Write and paste them into the Terminal (see the
Microsoft Windows User's Guide). You will receive error
messages from the printer.
• If the printer is to be controlled via MS-DOS, connect via either
the serial RS 232 port or the parallel Centronics port. You can use
the DOS Edit program to compose the commands. To print, use
DOS Edit's File/Print command or use the DOS Copy or Type
commands (see the MS-DOS User's Guide). You will not receive
error messages from the printer.
• If the printer is connected to a non-PC host computer, connect via
the serial RS 232 port. You can type commands directly into the
terminal or compose them in a text editor first. You will receive
error messages from the printer.
