Can I print with just black ink with my HP officeJet Pro 8725?
Yes you can but you must have the color ink cartridge to be able to print as this ink is used for periodic service task such as for cleaning printhead clogs or if you are facing a poor printing quality. To set the settings to print only in Black for all printing jobs. Open Device and Printers > right click on your printer and select Printer Preferences > Select your printer and click on Paper Quality/ Features. Click on Advanced > Print in Grayscale and select Black Ink Only > click the Black and White button.Click on OK (Make sure you do not select High Quality Grayscale after selecting Print in Grayscale as the printer uses both black ink and color ink to produce a high quality black printout)
