5.3 Batch Printing

Introduction
The term "Batch Printing" means the process of printing several labels
without stopping the media feed motor between labels. The labels may
be exact copies or differ more or less in appearance.
Before the label can be printed, the instructions must be processed into
a bitmap pattern. This involves scaling of fonts and generation of bar
codes. The bitmap pattern is stored in print buffers in the printer's tem-
porary memory.
The size of the print buffers is decided by the actual size of the print
window according to the setup in regard of "Media Size; X-start", "Media
Size; Width", and "Media Size; Length".
Obviously, when the labels in a batch are very similar, it will be useful
only to need to process the fi elds that differ. By editing the layout so the
variable data are processed last and using the
tions (see below), the time needed to process each new bitmap can be
decreased, allowing a higher print speed.
By default, you can break and resume the printing of a batch of labels by
pressing either the <Print> or the <Pause> keys on the printer's built-in
keyboard. Other methods for issuing a break instruction can be selected
as described in Chapter 6.18.
Clearing the Image Buff er
The image buffers store the bitmap pattern of the label between pro-
cessing and printing. The image buffers can be cleared partially or
completely by means of a

is the same alphanumeric designator as in the corresponding FIELDNO
instruction, followed by a mandatory % sign.
clears image buff ers completely and is useful to avoid printing a faulty label
after certain errors have occurred.
clears image buff ers from the corresponding FIELDNO instruction to the end
of the label and is used in connection with print repetition when only part
of the label should be modifi ed between the copies.
