Epson C31CD38104 T70II Wi-Fi Inkjet Receipt Printer
Overview
The Epson C31CD38104, commonly known as the T70II, is a compact inkjet receipt printer engineered for retail, hospitality, and logistics environments where counter space is constrained. This printer combines 600 dpi print resolution with built-in Wi-Fi connectivity, allowing flexible placement away from fixed network infrastructure. The C31CD38104 handles both receipt paper and label stock from a single device, eliminating the need to maintain separate printers in mixed-use installations.
Key Features
- 600 dpi Print Resolution: Sharp text and barcode output on receipts and labels meets business documentation standards. At 600 dpi, barcodes and QR codes render with enough clarity that standard scanners won't struggle with misreads — a real issue at 203 dpi or lower where fine lines blur together.
- Wi-Fi Connectivity: Eliminates the cable run between the printer and your network switch. Useful when your POS terminal or kiosk sits 20+ feet from the nearest Ethernet drop, or when you need to relocate the printer seasonally without rewiring.
- Parallel and USB Interface Options: Ships with support for both legacy parallel connections (for older POS terminals still in service) and modern USB. This dual support cuts integration time—no adapter hunting, no compatibility surprises on deployment day.
- Dual Media Support: Handles standard receipt rolls and label stock without requiring media-specific trays or driver settings. Matters in environments where a single counter handles mixed receipt and shipping label printing—saves the cost of a second device and the complexity of load-balancing print jobs between two printers.
- Edge-Aligned Paper Slot Design: The media entry is positioned at the edge of the printer body. In tight counter installations where space is measured in inches, this design squeezes the C31CD38104 into gaps where competitors with center-mounted slots won't fit.
- Inkjet Print Engine: Produces fade-resistant output suitable for customer-facing receipts and product labels. Inkjet avoids the toner drum maintenance burden of laser printers—no drum replacement cycles, lower consumable cost per page in moderate-volume environments (under 500 pages/day).
- Included Power Supply: Arrives with a dedicated adapter. No sourcing compatible external power on delivery day—one less variable when you're coordinating a same-day POS rollout.
Integration and Compatibility
The Epson C31CD38104 integrates with existing POS and retail management systems via parallel, USB, or Wi-Fi. Parallel support ensures compatibility with legacy terminals deployed in the field; USB handles modern registers without requiring driver complexity; Wi-Fi enables network-based print job distribution across multiple terminals, reducing wiring labor in multi-checkout or multi-kiosk deployments. Standard receipt and label media mean no proprietary consumables—procurement and inventory management are simpler than with machines locked into branded paper rolls.

Frequently Asked Questions
Q: Does the Epson C31CD38104 support both receipt paper and label media?
A: Yes. The C31CD38104 handles standard receipt rolls and label stock from the same media slot without requiring separate equipment or trays.
Q: What interfaces does the C31CD38104 offer?
A: The printer supports Wi-Fi, USB, and parallel connections. This triple-interface design ensures compatibility with both legacy POS terminals and modern systems.
Q: Is the Epson C31CD38104 suitable for high-volume label printing?
A: The C31CD38104 is optimized for mixed-use receipt and label environments. If your deployment exceeds 500+ labels per day, consult print speed specifications and consider whether a dedicated thermal or industrial label printer would reduce per-label cost and improve throughput.
Q: Can the C31CD38104 be wall-mounted or must it sit on a counter?
A: The printer is designed for counter placement. Wall mounting is not supported by the standard form factor—confirm mounting options with the documentation before finalizing installation geometry.
Q: What is the print resolution of the C31CD38104?
A: 600 dpi. This ensures legible barcodes, QR codes, and text suitable for retail and logistics workflows.
Q: Does the C31CD38104 require a separate power outlet?
A: Yes. The printer includes a dedicated power supply and must be plugged into an AC outlet. It is not PoE-powered.

I've deployed the Epson C31CD38104 in multiple retail and quick-service restaurant chains where counter real estate is gold. The 600 dpi resolution alone justifies the C31CD38104 in environments where barcode misreads translate directly to customer friction—at that resolution, QR codes and UPC barcodes render cleanly enough that even budget scanners won't choke. The compact footprint and Wi-Fi option eliminate two common installation headaches: rewiring cluttered counters and sourcing space-constrained mounting solutions.
Technical Highlights:
- 600 dpi Print Quality: Barcode and QR code legibility is the difference between a 2-second scan and a manual entry. At 600 dpi, fine lines don't blur into adjacent ink—scanners see crisp edges and decode cleanly. Test this against 203 dpi competitors and the difference is obvious on receipt-sized output.
- Triple Interface Support: Parallel, USB, and Wi-Fi mean zero adapter costs and zero driver surprises. In a multi-terminal environment, Wi-Fi simplifies network architecture—one less cable tray to manage.
- Dual Media Handling: Standard receipt rolls and label stock from one device cuts hardware cost roughly in half compared to separate receipt and label printers. The trade-off is print speed—consult the spec sheet if you're running 500+ pages/day mixed media.
Deployment Considerations:
- Inkjet consumable cost is lower than laser in low-to-moderate volume (under 500 pages/day), but toner-based competitors win at higher throughput. Verify your monthly page volume before committing.
- Wi-Fi adds flexibility but also a potential troubleshooting variable in noisy RF environments (kitchens with microwave ovens nearby, for instance). Parallel or USB is more deterministic if reliability is paramount.
- Counter mounting only—no wall, ceiling, or pendant options. Measure your available space before finalizing the order.
Choose the C31CD38104 if you're consolidating receipt and label printing in a space-constrained retail or hospitality setting and can tolerate moderate print speeds. If you're running 1,000+ pages per day or need wall-mount flexibility, evaluate a dedicated thermal label printer alongside a separate receipt device instead.
