One thing I have to ask is are these certified windows 10 drivers? or are you using previous OS drivers, as the actual 10 drivers are not available? The variable results you are getting could be due to the interaction required with the driver by Photoshop.
Photoshop stresses drivers far more that even other components of CS4
Unfortunately printer manufacturers are not known for the speed of release for drivers for new Operating systems, indeed many see a New OS as an excuse to sell more hardware by not updating drivers
