Answer to "Why is my printer not gettng any wifi"If you have tried the test page and it has printed out fine, but are still having issues you could be dealing with a connection issue. Printers can be connected locally or through a network. Local printers are typically connected by a USB while printers use a parallel cable. If you are using a USB, ensure that the USB cable is connected to both the printer and the computer. Try alternating the USB cable if you have another one handy, or use a different USB port if available. If the connection is still not working, then the USB or printer drive could possibly be corrupted. A corrupted USB is a software issue. Parallel cables are hardly used anymore, but if you are using one then ensure that the cables are connected firmly to both the printer and computer. Unlike USB, the parallel cable either works or does not work.
