When selecting a printer for a small to medium-sized enterprise (SME) that minimizes long-term costs, consider the following factors: initial purchase price, cost of consumables (ink or toner), maintenance costs, and energy efficiency. Here are some printer types and specific models that are often recommended for SMEs based on these criteria:

### Printer Types

1. **Laser Printers**: Generally have a higher upfront cost but lower cost per page, especially for black-and-white printing. They are ideal for high-volume printing.
2. **Inkjet Printers**: Typically have a lower initial cost but can have higher ink costs over time. However, some models offer high-yield cartridges that can reduce costs.
3. **All-in-One Printers**: These multifunction devices can print, scan, copy, and sometimes fax, which can save money on separate devices.
