Printing Manager Routines / Initializing and Validating TPrint Records

PrintDefault

When you create a TPrint record, you use the PrintDefault procedure to initialize the fields of the TPrint record according to the current printer's default values for resolution, number of copies, and so on.

PROCEDURE PrintDefault (hPrint: THPrint);

hPrint

A handle to a TPrint record (described on page 9-41), which may be a new record or an existing one from a document.

DESCRIPTION

The default values for the current printer are stored in the printer driver's resource file. The PrintDefault procedure puts these values in the TPrint record, replacing the ones that may already be there. The PrintDefault procedure calls the PrValidate function (described in the next section) to ensure that the TPrint record is compatible with the current version of the printer driver.

SPECIAL CONSIDERATIONS

You should never call PrintDefault between the pages of a document.

ASSEMBLY-LANGUAGE INFORMATION
