Component: TPdf · Unit: PDFium
Fires when a JavaScript doc.print call runs, exposing the full print parameters (page range, silent flag, shrink-to-fit, etc) so the host can drive its own print pipeline
Remarks
- The callback has no view context, so the host must locate the active TPdfView itself
- bUI indicates whether to show a print dialogue; nStart/nEnd are the 0-based inclusive page range
- Unassigned leaves the print request silently ignored
