Reprinting Labels

To reprint labels, submit the following batch with pclWrite:

{B, format, U, quantity|}

where

format

is the format number and

quantity

is the number

of labels to print.

Pausing While Printing

After submitting a packet that prints labels, an application

should pause until the printer becomes free. To check if the

printer is busy, the application calls pclStatus. By calling

pclStatus in a loop, the application pauses until the printer

finishes.

The following code illustrates how to pause the application

using pclStatus.

while ((iStatus = pclStatus()) == 1);

See “pclStatus” in Chapter 4 for more information.

Loading Multiple Packets Together

The application can load multiple packets together after it

initializes the Print subsystem. You can create one or more text

files containing any number of packets, and then pass those file

names to pclOpen. The application must call pclOpen only

once per file.

If the packet file contains a format and a batch, the call to

pclOpen also prints labels.

SAMPLE4.C in the Samples sub-directory illustrates loading

multiple packets together.
