Demo Label showing use of Print Utility Procedures
After the file Pal_Procs_and_Formats.txt has been copied to the printer, a number of new procedures are
now defined in the printer (until powered off). These procedures have been written specifically to
demonstrate how to use the Pal Print and Program operators to produce printed output. These procedures
also provide easy ways to print various objects without actually needing to know the PAL language. The
print utility procedures may be incorporated into custom programming or just used as reference to better
understand the Pal
TM Print and Program operators. After downloading Pal_Procs_and_Formats.txt to the
printer, copy the file Proc_Demo.txt to the printer. This file uses the various print utility procedures
defined to produce a demo label. Using a text editor, open the file Proc_Demo.txt file to see how these
various utilities may be used as shown in the demo label print sample below.
The interesting thing to note in the Proc_Demo.txt file is that the only actual PAL operator used is the
showpage operator. The other procedure names used such as Printfont and Printbarcode are not native
PAL operators but new procedures defined. A careful study of the definition of these procedures will
reveal the actual PAL operators used.
The basics of creating procedures and using them in the PAL language should start to make sense after
reviewing how the procedures are defined (in Pal_Procs_and_Formats.txt) and how they can be used (in
Proc_Demo.txt). New procedures performing virtually any task can now be written using the PAL
TM
Print and Program Reference manual for detailed information on additional PAL operators. The existing
procedures may be modified as needed to meet requirements or completely new procedures may be
written.
