Trouble Printing Datagrids from the Print Preview Window

I've got a C# Winforms app and I'm trying to print a datagrid using the technique found here: http://www.c-sharpcorner.com/Graphics/DataGridPrinterMG.asp So far the print functionality is working great, if we call it directly and the user clicks "Print" from the PrintDialog. The problem starts with the print preview. The grid is displayed fine in the preview window, but when the user prints from the PrintPreviewDialog by clicking the "Print" button, only the header row is printed out. This is really puzzling because if the grid is getting to the PrintPreviewDialog okay, it should print just fine because the print is a method of the PrintPreviewDialog, not my own code. Has anyone else experienced this problem? I could post the code, but there's a lot of it and it follows the article explicitly. Thanks in advance for your help!

I don't think you are going to be able to do much more than suggest your users not do that. I had the same problem with large images. The page rendered just fine in preview, but not on the actual printed page. Take a look at you printer setup. See if you have resonable margins. This can lead to problems if the preview thinks it has more room than the printer actually has. Also look to see if your printer has something like Page Protect. Some printer drivers will drop items if they are to be printed outside of the margins. I have seen cases where a printer driver reports the available space as just one pixel more than what can actually be printed. If an app tried to use that pixel, the printer would croak. One sure fire way to validate your code is to use a PDF printer if you have Acrobat installed. It is never subject to such problems.
