Clearing the Image Buffer
The image buffer stores the bitmap pattern of the label between
processing and printing. The image buffer can be cleared partially
or completely by means of a
CLL
command.
CLL [<field>%]
<field>
the same alphanumeric designator as in the
corresponding
FIELDNO
command, followed
by a mandatory
%
sign.
CLL
clears the image buffer completely
CLL <field>%
clears the image buffer from the correspond-
ing
FIELDNO
command to the end of the la-
bel
Complete clearing is useful to avoid printing a faulty label after
certain errors have occurred.
Partial clearing is used in batch printing when only part of the label
should be modified between the copies. In this case, the
CLL
state-
ment must include a reference to a field, specified by a
FIELDNO
command. When a
CLL
command is issued, the image buffer will
be cleared from the specified field to the end of the label.
<field>% = FIELDNO
<field>
the same alphanumeric designator as in the
corresponding
CLL
command followed by a
mandatory
%
sign.

↵
A%=FIELDNO

(cleared from the buffer after printing)
CLL A%
