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.

An application can use fixed packets or packets that change
every time they are used, such as in an application where the
operator enters the quantity for the batch. When packets
change every time they are used, the application must build the
packet dynamically.
SAMPLE3.C in the Samples sub-directory illustrates building
packets dynamically.

An application uses the printer’s scanner (either the 1222 or the
1223) to read bar codes as follows:
1. Enable the scanner with scnScannerOpen or
scnOpenScannerShared.
2. If necessary, configure the scanner using the scnGetx x x
and scnSetx x x functions.
3. Use any scanner function to operate the scanner. These
functions are described in Chapter 4 and all begin with an
scn prefix.
4. Disable the scanner with scnCloseScanner.
