I have an HP 2550L. My yellow cartridge light indicator is blinking and my blue and black lights are lit. I presume that indicates I'm out of yellow and low on blue and black.
I have a spare black toner but don't have any color toners.
I want to be able to print in greyscale only for the time being until I get some color toners. But it looks like the flashing yellow light is stopping me from printing altogether.
Is that true? Can I not print anything until I put in a new yellow toner?
