Functions and space: A print-only unit cannot replace a scanner. Compare unit dimensions rather than shipping-box dimensions, and leave the manufacturer's required operating clearance. Brother lists the HL-L3295CDW at 15.7 × 17.6 × 10.8 inches. Canon lists the MF665Cdw at 425 × 461 × 397 mm.
Workload: Use recommended monthly print volume, not the maximum duty cycle, for routine planning. Brother recommends up to 4,000 pages per month for the HL-L3295CDW; its 50,000-page maximum duty cycle is a different figure. Do not transfer these numbers to another model.
Larger office equipment: The Kyocera M8124cidn datasheet lists 590 × 590 × 753 mm and A3/Ledger capability. Confirm regional equipment and options. A larger copier may need more space, delivery planning and service support than a desktop printer.
Toner costs: Compare the price and declared yield of each replacement cartridge for the exact machine, with the same coverage assumptions. Include drums and other consumables where applicable. Starter cartridges are not a substitute for replacement-cartridge yields. We do not have a complete set of comparable current cartridge prices, so a precise cost-per-page ranking would be misleading.
Worked example: A hypothetical $90 cartridge rated for 3,000 pages gives $90 ÷ 3,000 = $0.03 per page for that cartridge alone. This is not a quote for a listed printer, and excludes other colors, drums, paper and differences in actual coverage.
