WR BLOB TO PRINT SETTINGS ( area ; printSettings ; paramType )

Parameter	Type	Description
area	Longint	4D Write area
printSettings	BLOB	BLOB containing the print settings
paramType	Longint	0 = layout and print, 1 = print

Description

The WR BLOB TO PRINT SETTINGS command replaces the current print settings of the 4D Write area by those contained in the printSettings BLOB.
The area can be an external window, an included area or an offscreen area. However, because of the mechanisms managing 4D Write print settings, this command cannot be used for all the areas by passing 0 to the area parameter.

The printSettings BLOB must have been generated by the WR Print settings to BLOB command.

printSettings contains two types of settings:

Layout parameters (paper, orientation, scale);
Print parameters as such (number of copies, paper source, etc.).

Note: Under Windows, the settings stored in the BLOB include the printer.

In the paramType parameter, you can pass one of the following constants, found in the "WR Parameters" theme:

Constant	Type	Value	Comment
wr layout and print settings	Longint	0	The print and layout settings are used
wr print settings only	Longint	1	Only the print settings are used

The new print settings are applied to the document present in the area.

Note: Print settings are not formatted in the same way under Windows and Mac OS. Consequently, the compatibility of the printSettings BLOB between the two platforms is not guaranteed.

System variables and sets

The system variable OK is set to 1 if the BLOB has been loaded correctly and 0 if not.

Error management

If no printer is selected, the error 1014 is generated. If the printSettings BLOB does not contain valid print settings, the error 1074 is generated.
