Intermec EasyCoder 301 Direct Protocol 2.0 – Programmer's Guide Ed. 3
The verbosity level controls the amount of information to be re-
turned from print to host:
SYSVAR (18) = <value>
<value> = -1
<value> = 0
<value> = 1
<value> = 2
<value> = 4
<value> = 8
Bits can be combined, so e.g. SYSVAR(18)=3 means both "Echo
received characters" and "Ok after correct command lines".
Four types of error messages can be selected:
SYSVAR (19) = <value>
<value> = 1
<value> = 2
<value> = 3
<value> = 4
By default, the Intermec Direct Protocol error handler handles four
error conditions:
• Out of paper
• Head lifted
• Out of transfer ribbon
• Next label not found
All other errors are ignored unless specified by an ERROR com-
mand.
When an error occurs, the standard IN channel is flagged as busy
and the Power LED changes from Green to Red. The message speci-
fied for the error by the ERROR command is sent to the standard
OUT channel. In the case of the four error conditions listed above,
a standard message in English will be sent to the host computer if
no other message is specified by an ERROR command.
When an error occurs, press Feed to acknowledge the error, then
correct it, either in setup or physically, e.g. by changing the transfer
ribbon.
