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.

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.

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.
