There is a question about print as follows:

I have exported a dxf file in librecad,when  i printview and click "fit to page" ,there is a message as follows:
Warning:: Paper size less than 10mm. Paper is too small for fitting to page
Please set paper size by Menu: Edit->Current Drawing Preferences->Paper
RS_ActionPrintPreview::fit(): Invalid paper size

I want to konw how to solve

Have you set the right paper size in the current drawing preferences as asked for in the message? If not do so and try again.
