Now power on the computer first, and wait until it is fully rebooted. Now connect the printer back to the computer and power it on. Ensure that the printer lights are on. This should let the computer detect the printer and hence resolve 123.hp.com printer problems. Power cycling resets the software and applications and hence fixes printer issue most of the times. If the error shows the printer is offline, right click on the 123.hp.com printer's icon > select 'Properties' from the drop-down list, and check if the printer is offline. If it is, then put it the online mode. If this does not work, update the printer drivers from the manufacturer's website (viz. Canon, HP, ..). This should resolve the problem as non-updated drivers stop the printer from functioning smoothly.
