Notes: The TPrint structure is the basic "print record" used by the Printing
Manager. A handle to a TPrint is used in the following functions:
Use NewHandle to allocate storage for the structure and follow it with a We are explicitly warned that this structure (including its sub structures)
is likely to change in the future. With very few exceptions, the print
record should be handled as a "read-only" structure. The Print Manager
dialogs will take care of letting the user select the various options, and some
complicated interactions take place between the Printing Manager, the
dialogs, and the Printer Driver. See PrOpenPage for the most common exception to the "read-only" rule.
It is advisable to save a copy of the TPrint record (after running it through
the print dialogs) when you save a file. The next time a user wishes to
print the document, read it from the file and call PrValidate to ensure its correctness.
