I run CorelDraw 2019 and we just purchased an HP Color LaserJet M751. I have installed the PS driver HP provides, but am unable to print in halftones. We had used an HP LaserJet 5100 and that worked fine. I know there is a setting either on the printer or in Corel to allow the app to control postscript. Any help?
way back in the day we would convert the image to Black & White bitmap and use the LPI to set the halftone, would that be a good workaround for you?
