Printing in black and white
For people who want to save on ink cost maybe this can help. I went to buy a replacement color cartridge for my HP printer and found it was $40. WOW! I will not pay that. Several people told me I can't print without it, I replaced my last printer because it wouldn't print without the color cartridge. I tried gray scale and that didn't work. Finally one clerk told me I can, I just have to find the option. So I kept looking and found the little down arrow under the gray scale option. When I clicked on it, there was an option for black and white only. Worked.
I read that the manufacturers hide options that they think we shouldn't mess with. In this case I think HP wanted that $40.. LOL
