Welcome to the HP support community.

I understand that your printer is printing blank pages, I am glad to assist you.

Did you make a copy and check if that prints fine?

Meanwhile:- 

Run the automated printhead or ink cartridge cleaning tool

• Clean the printhead and cartridges to resolve print quality issues including incorrect colors, streaks, and faded prints.
• Load plain white paper in the tray.
• Open the HP Smart app, and then click the picture of your printer to open the settings and management tools.
• In Print Quality Tools or in Advanced Settings > Tools > Utilities > Print Quality Toolbox, select Clean Printhead to start the cleaning tool.
• Review the Print Quality Diagnostic page that prints for defects and any instructions to resolve the issue. Run up to two more cleaning cycles, if necessary.

Clean the ink cartridge and carriage electrical contacts

• Remove any debris or buildup from the contacts on the cartridges and in the carriage.
• Open the ink cartridge access door on the front of the printer.
• 
• Gently press down on the cartridge to release it, and then pull it out of the slot.
• 
• Holding the cartridge by the sides, remove any protective tape that still might be on the contacts.
• CAUTION: Do not touch the ink nozzles or the copper-colored electrical strip. Touching or trying to remove these parts can result in clogs, ink failure, and bad electrical connections.
• 
• Lightly dampen a lint-free cloth with distilled water, and then wipe the copper-colored contacts on the cartridge.
• 
• Lightly dampen a lint-free cloth or swab with distilled water, and then clean the electrical contacts in the carriage.
• 
• Wait 10 minutes for the contacts to dry, and then reinsert the cartridge into its color-coded slot.
• Repeat these steps for the other cartridge if it was indicated in an error message.
• Close the door to the cartridge access area.
