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
TM 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 TM 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 TM operator used is the showpage
operator. The other procedure names used such as Printfont and Printbarcode are not native PAL TM operators but new
procedures defined. A careful study of the definition of these procedures will reveal the actual PAL TM operators used.
The basics of creating procedures and using them in the PAL TM 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 TM operators. The existing procedures may be modified as needed to meet
requirements or completely new procedures may be written.
