A very simple command to check the ink level of your HP printer or multifunctional.
Just type in the terminal 'hp-levels' and you know your ink level.
Thanks! It worked for HP 1018 Laser printer! Since I printed only some 50 pages, I assume the 100% level is correct.
easy and useful. I cannot cross check since I do not have HP inkjet ;)
Useful thing to remember. Thanks
