Hi, I am Sofia Carter, Printers not printing in black ink is a common issue caused in most printers. The issue is caused due to low black ink in the cartridge. So to fix the hp printer printing blank pages ink problem, you just need to refill your ink tank or replace the ink cartridge. If there’s enough ink in the printer and it’s still not able to print then check if the black ink is clogged. In that case, too you will need to replace the ink cartridge. Start with restarting your printer and computer to fix any temporary glitches.
