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 using a CLL command.
CLL [<fi eld>%]
<fi eld>
CLL
CLL <fi eld>%
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 modifi ed between the copies. In this case, the
CLL statement must include a reference to a fi eld, that is specifi ed
by a FIELDNO command. When a CLL command is issued,
the image buffer will be cleared from the specifi ed fi eld to the
end of the label.
<fi eld>% = FIELDNO
<fi eld>
