The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
On the printer control panel, press the OK button to display the Home screen. Use the arrow buttons to navigate to and open the following menus: Setup → Network Setup → General Settings. On the General Settings menu, select Show the IP Address, and then select Yes to display the printer`s IP address or host name.
The printer could be dirty. Solution: Arrange to have your printer cleaned. The toner cartridge may be nearly empty. Solution: Replace the toner cartridge.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

Check cables or wireless connection

Make sure that the printer`s USB cable is properly connected from the printer to your PC. If your USB isn`t recognized, see Automatically diagnose and fix Windows USB problems. Check the wireless connection (for wireless printers).

Error Code 3 is a Windows error code that appears when the computer cannot find the specified path.
C# enum PrinterStatus { Other = 1, Unknown, Idle, Printing, Warmup, Stopped Printing, Offline } So the result that you are getting (3) means it is Idling.
The factory defaults include a TCP/IP address of either 169.254. x.x or 192.0. 0.192. Some print servers may show the TCP/IP address as 0.0.
Wi-Fi printers

Go to the Start menu and click Settings, Devices, then Printers & scanners. Select Add a printer or scanner and wait for your printer to appear in the list, then select it and hit Add device. If Windows doesn`t find your printer, select The printer that I want isn`t listed and follow the instructions.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.

Print Quality Issue (Streaks and Ghosting)
ANSWER : Streaks are mostly caused by internal drum wiper blades that clean left over toner off the drum to prepare it for a new image. Ghosting is caused by a leftover image on the drum. The 6 inches that you mention would be the circumference of the part that is causing it. Fusers will never cause either problem.
