My wife has an Acer computer a little over 1 year old. She had a HP printer from the old computer and hooked that to her new computer. Shortly the printer died and HP replaced it under warrentee. The new printer has been supplied with HP ink via the HP online ink program. Fast forward to about a year later. Printer quit responding to computer requests to print. I found that the wireless connection quit working - (again). So today I hardwired the printer to the computer to end that problem. When printed a test page there was no black ink used in the print. So the page was blank since no color on that page. Replaced ink cartridge with new one. Still didn't work. So went and purchased a new cartridge - - it still didn't print black. Did full maintenance on the printer - nothing. Has anyone here had this problem and were they able to correct the problem? Computer Acer Operating system Windows 10 Printer HP officejet pro 6830.
