Can I use the office printer?
'Stampante' = stam-PAN-teh. Four syllables; stress the second.
Use this any time you need to use shared office equipment. Always ask before using equipment that belongs to the office, especially as an intern. It shows respect for company resources.
'Posso' + infinitive is the most natural way to ask for permission in Italian. 'Dell'ufficio' (of the office) specifies it is the shared company printer, not a personal one.
