[Fixed in 9.5.20] Score printing problem

I have been doing a lot of printing over the past week and have not experienced any issues, so it’s likely the the issue is not with Cubase itself, but with how it interacts with the printer. There are many different printer drivers, I have a Brother 5150D and all is good.

What I would do in your position is check the page layout dialog, and remove and reinstall the printer driver.
