Null reference exception on print preview when no printers are installed

Question

Hello,
I noticed this problem while testing V3.3.0.0 on a "clean machine" which happened to have no printers installed.

In the print sample, clicking the print preview button caused a null reference exception.

This problem was also present in V3.2.1.0 but I forgot to report it.

Hi Richard,

We are aware of this issue, and will fix the problem before the next release of Essential Diagram. We hope to have a minor update of Diagram to be made available within the next 2 weeks, and this will feature a gracious way of exiting print commands when a printer is not installed.
Thank you for putting this problem on our radar again.

Thanks,
