Printer MX922

I buy the canon Pixma MX922, I think that I can print fron anywhere with my laptop, tablet or phone, but I only can print from my network.  I will someone that can help me with that.

This printer don’t change fron copy to fax when a fax coming in, canon people say I have to be infront ot it and select fax and then Hook and black.  Need help hear too.

Let me now if some of this thinks can be fix, if not maybe I will send the printer back.

Thank you.
