About 5 days ago my Envy 4520 lost the option to change printing options through the usual Printing Preferences Paper/QualityTab! Frustrating, as I have tried the usual uninstall/install etc. and no joy and no solution apparent here or elsewhere. Windows Troubleshooter and HP Print and Scan Doctor both show no fault. I can get a colour test page directly from the printer, but only B&W from the computer. HP Smart, Word, Acrobat, photos etc all have lost the colour print/greyscale/B&W option. Help please!
