- Check printer is turned on and connected
Make sure that your printer is switched on, connected and that its power light is on. Check that it is connected correctly, both the power cord and the data cable. Make sure that is switched to the correct port of any USB splitter. - Check to see ink is at appropriate levels
All printers will have an indication of current ink levels, usually this appears on the printer's display panel. If it is low, make sure to restock the cartridge with the required type of ink. - Check paper levels
If there are no issues with the printer's connection, ink or power, then check the paper tray levels. If the tray is empty, open the tray to add paper or replace as necessary. - Test printer
If everything is connected correctly, check ink and paper is at appropriate levels and you still cannot print, then print a test page. This is usually found in the printer's settings menu or in your computer's printing preferences menu.
