Check your paper size settings.  This issue is usually because the paper settings in the printer don't match what your print driver thinks you have.  In other words, the print driver thinks that you have plain paper in tray 2, but your printer thinks it has heavy paper in tray 2.  The reason you have to hit continue is because the printer is waiting for you to load the correct paper.

You should check it in the paper/tray assignments on the printer, which can be done on the printer itself, or in the printer web interface, and also check the printer properties in the computer trying to print to make sure they are both set the same.

Works now, thanks.
