Printer Issues

My company recently upgraded to Corel X6 from X3 and we have started developing a printer issue that seems intermittent for lack of a better description. 

It seems like when I go to print out proofs for customers that occasionally I only get parts of the document printed to paper. I have found a work-around by converting everything to curves before I print, but that seems to be a patch rather than a true fix. I didn't have any of these problems with X3 and I'm sure that is is probably a simple fix, but I am at a loss as to how to go about fixing it. 

It also seems to happen more when text has been formatted like fit to path or there are vector logos on the print. I mainly work in black and white as a large amount of my work is burned by a laser and made into stamps and plaques, but the problem follows both my Brother Laser Printer MFC-L8850CDW and my Universal Laser V400.

Any suggestions on where to look for corrections would be greatly appreciated.
