I was trying to use the Print Preview->WYSIWYG printing of the complete grid dialog and made some observations.
The preview window always opens a tiny window showing a full page at an illegible 18%. It would be nice if it remembered it's size and position.
There does not appear to be any way to change printer options, it always prints to the default printer using the default settings. I have a print to pdf driver installed that I wanted to use, but it went to my default inkjet. The Print button should show a standard print dialog.
If a field in the grid being shows is wider than the page it will insert a blank page. Maybe it would be possible to add some kind of optional auto-scaling to the dialog?
Or it might be better to avoid this preview dialog all together and always export to html and use the much nicer html print preview dialog?
