I dowloded the latest drivers for the above printer however after following all the relative instructions I cannot print wireless. The laptops run on Centos 7 x64 and Lubuntu x32 and previously worked perfectly using a HP printer. I do not have the same problems when I use a cable network connections connected to my desktops that run Windows 10, Fedora and Ubuntu. It appears that the wireless connection works well when I use a laptop that runs on Windows 10. I believe that the printer configuration is correc otherwise it would have not been working when using Windows 10 on my laptop wireless. Thank you in advance
