Buyers should prioritize print resolution (typically 1200 x 1200 dpi or 3600 x 1200 dpi equivalent) for high-definition output. Evaluate the duty cycle, ensuring the machine can handle your monthly volume (e.g., 150,000 to 1,000,000 pages). Check for Simitri HD polymerized toner compatibility, which ensures superior image quality and lower environmental impact. Additionally, verify the media weight support, as professional units should handle up to 350-400 gsm for packaging and business card applications.
