For double-sided printing, select manual duplex in the print driver and follow the on-screen instructions. Keep a spare HP 142A toner cartridge on hand to avoid downtime, and clean the scanner glass regularly for crisp copies and scans. Place the printer within range of your Wi-Fi router for stable wireless performance.
