Printing Errors or Lights & Stuck Print Jobs

I have a new HP Deskjet 2600 printer that abruptly started printing blank pages. I made a test print and found that it still prints in color. The HP app bar graphs shows that the black cartridge (cartridge that came with the printer) is approximately 15% full. The app gives no indication of any problem. I ran the Windows 10 troubleshooter, it reported that the system is working properly.
Complicating the situation this printer had recently had problems printing document. I noticed recently that the printing process was taking an increasing amount of time to do its work. Instances had been occurring occasionally. When starting a print job there would be a long delay before hearing the carriage beginning to move. On other occasions a long delay would occur after the carriage stopped. Additionally on still more occasions the printer did nothing after sending the print command. After that, sending a second or third print command. Those too failed to start the printing process. Going further on some occasions toggling the printer power button off and on might start the printer working. These delays can take between 1 and 4 minutes, 4 minutes being the point I shut down the print job. Occasionally after toggling the power switch the printer will print multiple copies of the document.
I have learned that many other users of this printer have experienced the same problem. This appears to be a communication problem. My printer is connected by the USB cable and PC 3.0 port. I'm guessing that the HP app is getting incorrect ink cartridge levels measurements from the cartridge. Does anybody recognize this problem. Tnx
