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>
CLL
CLL <field>%
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>
