WP PRINT
WP PRINT ( wpDoc {; printOptions} )
| Parameter | Type | Description | |
|---|---|---|---|
| wpDoc | Object | → | 4D Write Pro document |
| printOptions | Longint | → | Printing options for the 4D Write Pro document |
This command is not thread-safe, it cannot be used in preemptive code.
Description
The WP PRINT command launches a print job for the 4D Write Pro document specified in wpDoc, or adds the document to the current print job if it is called between OPEN PRINTING JOB and CLOSE PRINTING JOB. WP PRINT uses print settings defined by the 4D PRINT SETTINGS or SET PRINT OPTION commands, except for page margins which are always based on the 4D Write Pro document page settings. WP PRINT uses current page setup options (such as page size and orientation), or those of the document if WP USE PAGE SETUP was called previously.
The optional printOptions parameter can be used to set the HTML WYSIWYG view for the print output as well as the formula computing. You can pass one or a combination of the following constants from the "4D Write Pro" theme:
| Constant | Type | Value | Comment |
|---|---|---|---|
| wk 4D Write Pro layout | Longint | 0 | Standard 4D Write Pro layout, which can include some specific style attributes |
| wk do not recompute expressions | Longint | 2 | Specifies that all expressions in the document are not recomputed before printing or freezing. |
| wk html wysiwyg | Longint | 1 | In this layout, any 4D Write Pro advanced attributes which are not compliant with all browsers are removed (e.g. columns, double underlines...) |
| wk recompute expressions | Longint | 0 | Specifies that all expressions in the document are recomputed before printing or freezing (default value). |
If printOptions is omitted, by default the 4D Write Pro layout is used and expressions are recomputed (if any).
Note: When printed with WP PRINT, 4D Write Pro documents are always printed as in Page view mode, regardless of the View property setting for the area (see Configuring View properties).
Compatibility Note: The GDI-based legacy printing layer (which can be set using the SET PRINT OPTION command) is deprecated and should not be used with WP PRINT, since it may result in rendering artifacts. It is recommended to only use the default printing layer with this command.
Example
You want to print a 4D Write Pro document in standard or HTML wysiwyg layout depending on the value of a variable:
// print using a specific layout HTML wysiwyg or 4D Write Pro Layout
If(rb_htmlwysiwyg=1)
WP PRINT(writeProDoc;wk html wysiwyg)
Else
WP PRINT(writeProDoc;wk 4D Write Pro layout)
End if
