My HP laser printer is printing in grey. I just unhooked it from my other pc and it printed fine today. I have lots of toner. Just printed about 100 pages on my other computer, so that's not the problem. This cartridge prints about 2000 pages. Also, i went through the printer manual troubleshooting steps, but still is not working. So i unhooked it again and connected it to my older pc and printed a page and it was black. Re-hooked on this newer pc and it's printing grey still. Can someone please help? I have a 1059-page transcript i need to print by morning. help help help
Thank you in advance
