Intermec EasyCoder 301 Direct Protocol 2.0 –Programmer's Guide Ed. 3

Chapter 1

Introduction

IntermecDirectProtocolis aneasy-to-useprinter programminglan-

guage that has been developed for use with the computer-control-

led direct thermal and thermal transfer printers manufactured by

Intermec.The versiondescribed inthis manualis onlyapplicableto

EasyCoder 301 printers, but is in most respects compatible to other

versions of the Intermec Direct Protocol, so applications created

for other types of EasyCoder printers can be used on an EasyCoder

301 with few or no modifications.

Intermec Direct Protocol can be used 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 commands as a continuous

string of data directly from the host computer.

In both cases, Intermec Direct Protocol provides a flexible error

handler, which allows you to compose your own error messages in

any language.

Intermec Direct Protocol has been created with two main types of

application in mind:

• Applicationswheretheend-userrequiresasimpleprintercontrol

program, but needs a versatile error handler.

• Applicationswhichhaveacomprehensiveprintercontrolprogram

in the host computer.

Referto chapter13in thismanualfor listsof thevarious commands

in Intermec Direct Protocol.

We recommend that you have the following manuals accessible

when you perform any programming:

• EasyCoder 301 Installation and Operation Manual

• This Programmer's Guide.

Intermec EasyCoder 301 Direct Protocol 2.0 –Programmer's Guide Ed. 3

Chapter 2

Intermec Direct Protocol is stored in two Flash EPROM packages

fitted as standard on the printer's CPU board. No floppy disks or

operating system, such as MS-DOS, are required. The printer only

needs to be connected to a mains supply and to a device capable of

transmitting characters in ASCII format, which can be anything

from a non-intelligent terminal to a mainframe computer system.

For running the printer, we recommend a computer with a screen,

an alphanumeric keyboard, and a communication program which

provides two-way communication via an RS 232C serial port. A

Centronics parallel port can also be used, but it will provide one-

way communication only: no data or messages can be returned to

the screen of the host.

Connect the printer and host as described in the EasyCoder 301

Installation and Operation Manual.

It is possible to set up the printer's communication protocol to fit

the host computer, as described in the EasyCoder 301 Installation

and Operation Manual. However, until you have become familiar

with Intermec Direct Protocol, it may be easier to adapt the host to

the printer's default setup parameters. There is no communication

setup for the Centronics parallel interface.

Default serial communication setup on "uart1:"

• Baud rate.................... : 9600

• Parity ......................... : None

• Character length ......... : 8

• No. of stop bits ........... : 1

• Flow control............... : Disabled

• New line .................... : CR/LF(CarriageReturn+LineFeed)

Getting Started

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.

Checkthattheprintheadislowered.Turnonthemainsswitch,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$ ↵

Providedyouhaveserialtwo-waycommunication,theprintershould

respondby immediatelyreturning theversion ofthe installed Inter-

mec Direct Protocol firmware to the screen of the host, e.g.:

V2.00

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,

andcheck iftheconnection ismade betweenthe correctports. 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" ↵

PT "ABCDEFGHIJKLM" ↵

Chapter 2 Getting Started

Each line will be acknowledged by “Ok” on the screen, provided it

has been entered correctly. When you press ↵ (Carriage Return)

the third time, the printer will feed out a label, ticket, tag or piece of

strip with the text printed in the lower left corner of the printable

area.

You can try using other characters between the quotation marks in

thethirdline,especially typicalnationalcharacterslike ÅÄÖÜ¿¢¥ç,

etc. If any unexpected characters are printed, you may need to se-

lect another character set (see chapter 6.11), or change the commu-

nication setup from 7-bit to 8-bit character length.

Principles of Operation

There is a built-in error handler, that can indicate selected error

conditionsand produce error-messages of your own creation in any

language you like.

Variable input data (in a special format) can be inserted into fields

in a predefined layout.

You can create counters without extensive programming.

You can easily enable the Feed key to produce printouts.

By default, verbosity is turned on in Intermec Direct Protocol1.

IntermecDirectProtocolallowsyoutosendcommandstotheprinter

in two ways:

• Immediate Mode

• Layout Mode

•Immediate Mode

You send commands that the printer will act upon immediately.

This method is used for setting up the printer, for returning

information from the printer back to the host and for managing

files, fonts and images.

Examples:

PRINT KEY ON ↵(enable Feed key)

? DATE$ ↵(read printer's calendar)

KILL "LAYOUT1" ↵(delete a layout or file)

Immediate Mode can also be used for creating label layouts

including all the printable data as illustrated below.

•Layout Mode

Layout Mode is only intended for creating labels. Firstly, create

a layout containing formatting commands for a number of fields

andsuchprintabledatathatyoudonotneedtochange.Secondly,

send a string of printable data to the empty fields plus a print

command. You can create a number of different layouts, select

the one you need, add the variable data and print out the labels.

1/. While you are experimenting

with Intermec Direct Protocol,

we recommend that you retain

thedefaultverbositysetting(ON).

Later you should change it to

OFF, since this will produce

optimum printer performance.

Chapter 3 Principles of Operation

Letus create thesimple label shownon the left usingboth methods:

Immediate Mode

You can send the string as a single line:

BF ON:BF "Swiss 721 BT",9,0:PP 10,20:

PX 400,300,10:PP 25,25:PM "ROM:GLOBE.1":

PP 75,250:BT "CODE39":PB "ABC":PP 75,200:

FT "Swiss 721 BT",9,0:PT "My FIRST label!":

PF ↵

You can also send the same string line by line:

BF ON ↵(enable bar code interpretation)

BF "Swiss 721 BT",9,0 ↵(select bar code interpr. font)

PP 10, 20 ↵(insertion point for box field)

PX 400,300,10 ↵(create a box)

PP 25,25 ↵(insertion point for image field)

PM "ROM:GLOBE.1" ↵(select image)

PP 75,250 ↵(insertion point for bar code field)

BT "CODE39" ↵(select bar code type)

PB "ABC" ↵(input data to bar code field)

PP 75,200 ↵(insertion point for text field)

FT "Swiss 721 BT",9,0 ↵(select font for text field)

PT "My FIRST label!" ↵(input data to text field)

PF ↵(print one label)

Layout Mode

First, create a layout:

LAYOUT INPUT "LABEL1" ↵(start layout recorder)

BF ON ↵(enable bar code interpretation)

BF "Swiss 721 BT",9,0 ↵(select bar code interpr. font)

PP 10,20 ↵(insertion point for box field)

PX 400,300,10 ↵(create a box)

PP 25,25 ↵(insertion point for image field)

PM "ROM:GLOBE.1" ↵(select image)

PP 75,250 ↵(insertion point for bar code field)

BT "CODE39" ↵(select bar code type)

PB VAR1$ ↵(variable input data to bar code field)

PP 75,200 ↵(insertion point for text field)

FT "Swiss 721 BT",9,0 ↵(select font for text field)

PT VAR2$ ↵

(

variable input data to text field)

LAYOUT END ↵(save layout)

Note:

If a label has been printed using

apredefinedlayoutandyouwant

toreturntoImmediateMode,the

predefined layout must first be

cleared from the printer's

working memory using the

following command:
