When print jobs remain stuck in the printer queue despite successful network communication (indicated by successful ping replies) and no issues with paper supply or toner levels, a common reason can be that the first job in the queue requires manual intervention, such as paper to be fed into a manual feed tray. Printers often pause the entire print queue if the first job requires a specific type of paper or manual insertion that hasn't been addressed, preventing subsequent jobs from processing.

For network printing, the required ports are typically those used by printing protocols. Port 515 is used by the Line Printer Daemon (LPD) protocol, and port 631 is used by the Internet Printing Protocol (IPP). These ports need to be opened in the firewall to allow print jobs to be sent to and from network printers.

If a desktop PC shuts down suddenly and there is a burning smell coming from the area where it is connected to the wall socket, the first step should be to check that the power cable is not damaged. A damaged power cable can cause electrical shorts or overheating, leading to sudden shutdowns and a burning smell. Inspecting the power cable for fraying, cuts, or other damage can help identify if it is the source of the problem.
