Operating System: Microsoft Windows 10 (64-bit)

Hello,

My WIFI printer shows in HP Smart as "online (green bullet)". When I send a test page, it shows Printing-Error.  I checked, the port number is correct, I have the latest drivers.

As a side-note, this printer is installed (and it works) when connected to USB cable.

I tried the WiFi installation several times (using TCP/IP option) but each time the Port changed by adding a "_1 or _2" because the initial port was used.  I also tried to remove the ports but every time I get the message "port is in use" even though there is no printer assigned to that port, that I can see.  Another interesting fact is that when I try to print a document, the list of available printers is now 5 printers when in fact I only have 2 (one USB related, the other WiFi).  However, in devices and Printers I still see the 2 printers I mentioned (not the 5 listed in the printer selection when I try to print a document).

So, how do I make my WiFi printer to print?  According to HP Smart it is active.  However, in HP Smart it has a name that i don't see in Devices and Printers . . .

Hope I did not confuse you . . .

 

Thanks!
