Connection issues

Hi all,

Couple of questions from a brand new OpenSuse user and relatively inexperienced Linux user.

Just installed 42.1
Cannot get HP printer to connect. Officejet that was connected fine using Ubuntu and HPlip previously.
Using the HPlip wizard it doesn’t find the printer at all. Is this something to do with the firewall?

Using KDE connect to connect android phone but it seems only one way - from phone to laptop. When I click OK on the KDE connect control panel, it disappears. Is this supposed to be like Airdroid and a two way connection? Only using this because again the laptop cannot access the phone via USB connection. This is my preferred connection method. Any ideas how to do this?

Kontact and Google 2 step verification. Email on Kmail is working fine but obviously there would be a separate app specific p/w generated by google for the calendar. - can I give Korganiser a different app p/w to the one that Kmail uses? Korganiser cannot acccess my calendar. Any ides how to set this up?

And, for UK Linux users, what’s the best monthly Linux magazine I can subscribe to?

Thanks in advance.
Have to say I love Suse and really hope I can this all working.
