Hello and welcome to the forum!
For 'wireless' printing, Apple's
Air Print technology is certainly a great option, but your printer must be compatible - check
HERE to learn more about 'Air Print' and also review the list of compatible printers to see if you have one?
If your printer is not 'Air Print' compatible, then a number of other options exist; for myself, I use a program called
FingerPrint (check
HERE) for further information - the cost for me was $10 for the older version (the price has doubled for the new release). The program resides on your computer only - functions well w/ my two USB wired printers.
Hopefully others will 'chime in' w/ additional suggestions - good luck! :thumbs:
