Yes, we need the HP Smart app for HP Deskjet 3755 Printer Setup as it helps users in connecting their printer, install printer driver, and diagnose and fix main issues. It also helps in printing scanning, faxing, and sharing files. It is a highly recommended app for many HP printer setups and installations. https://123hp-setup-com.us/hp-deskjet-3755-printer/
