I've had a few reports of printing issues in 10.14. It appears that solving DPI related issues on the screen display for Windows 8 and Windows 10 *caused* some DPI issues when handling the printer. These have subsequently been addressed in the beta for 10.15.
Can you please give this update a try and let me know whether it works for you?

This is a beta version. Please do not deploy it in production, as it will time out at the end of this month. Final release for 10.15 will occur by then, at which time you can deploy it more widely.
