Epson C31CC79551 Wireless Mobile Receipt Printer
The Epson C31CC79551 is a portable, Bluetooth-enabled thermal receipt printer engineered for mobile point-of-sale deployments where traditional hardwired terminals are impractical. This 2-inch receipt printer delivers monochrome output at 203 dpi resolution with a print speed of 236.2 inches per minute — fast enough to keep transaction lines moving during peak service hours without requiring extensive wait time for receipt generation. Built around direct thermal technology, the C31CC79551 eliminates ribbon cartridge management, reducing consumable overhead to thermal receipt paper alone.
Key Features
- 236.2 IPM Print Speed: Monochrome throughput at maximum velocity means receipt issuance completes in seconds, not minutes — critical when handling high-transaction-volume environments like hospitality venues or delivery-verification workflows where customer wait time directly impacts satisfaction.
- Bluetooth Wireless Connectivity: Native iOS Bluetooth pairing enables direct device-to-printer communication without requiring USB infrastructure, network setup, or proprietary gateway hardware. A tablet or iPhone pairs, sends print jobs, and disconnects — no complex onboarding required.
- 203 dpi Print Resolution: Monochrome thermal output at 203 x 203 dpi ensures barcodes render legibly for scanning at point-of-sale and in logistics workflows, text remains sharp for customer readability, and graphical receipts (promotional stamps, logos) don't degrade.
- 2-Inch Compact Form Factor: Optimized for standard 80-millimeter thermal receipt media, minimizing both paper waste and storage footprint. Lighter paper rolls fit portable devices, and roll logistics simplify when deploying dozens of units across multiple venues.
- Direct Thermal Print Method: Eliminates thermal-transfer ribbon cartridges and associated supply-chain complexity. Only consumable is the receipt media itself — no ribbon changes, no wasted ribbon cartridges in landfills, no mid-transaction ribbon failures.
- Mobile-First Design: Lightweight, battery-capable (evidence indicates portable operation), and rugged enough for tableside ordering, field-service ticket issuance, and delivery-signature capture in warehouse and logistics operations.
Integration & Connectivity
The C31CC79551 connects via Bluetooth, pairing directly with iOS devices running compatible point-of-sale applications. No network switch, no Ethernet drop, no PoE power requirement — deployment consists of charging the unit and pairing the mobile device. This architecture is particularly effective for hospitality venues running Square or Toast on iPads, delivery services verifying signatures in the field, and retail environments requiring mobile checkout. The printer operates as a wireless peripheral, meaning jobs can be queued from the front-of-house while the device remains in reach of the paired tablet or phone.
Deployment Scenarios
The Epson C31CC79551 addresses three primary use cases: (1) tableside ordering in restaurants and bars, where servers take orders on tablets and print receipts at the table without returning to a fixed terminal; (2) delivery verification in logistics and e-commerce, where field staff print proof-of-delivery signatures and package labels without returning to the truck; (3) mobile retail pop-ups and kiosks, where a cart or temporary stand requires fast, ink-free receipt printing without complex electrical setup. In each scenario, the 236.2 IPM speed and direct thermal efficiency keep operational friction minimal.

Frequently Asked Questions
Q: Does the Epson C31CC79551 support Android devices, or is it iOS-only?
A: The evidence confirms native iOS Bluetooth support. Android compatibility is not documented. Verify with Epson or your point-of-sale software vendor before deploying on non-iOS platforms.
Q: What is the maximum print width on the C31CC79551?
A: The printer is optimized for 2-inch (50mm) thermal receipt media, which is the standard width for this class of mobile receipt printers. This is the native media format; wider media formats are not supported.
Q: How long does a single charge last on the C31CC79551?
A: Battery runtime and charge capacity are not specified in the available documentation. Contact the manufacturer for battery endurance estimates based on your expected transaction volume and print frequency.
Q: Can the C31CC79551 print barcodes and QR codes?
A: Yes. The 203 dpi resolution is sufficient for standard 1D and 2D barcode rendering. Barcode quality depends on the point-of-sale application's barcode encoding and the printer's ability to render fine lines accurately at this resolution — test with your specific receipt templates before large-scale deployment.
Q: Is the C31CC79551 covered under Epson's standard warranty?
A: Warranty terms are not specified in the available documentation. Consult Epson's product support or your distributor for warranty coverage, replacement parts availability, and service options.
Q: What is the cost per receipt when using the C31CC79551?
A: Operating cost depends on thermal paper pricing in your region and your venue's transaction volume. Direct thermal consumable cost is typically lower than thermal-transfer ribbon-based systems because no ribbon waste is generated. Obtain current thermal receipt media pricing from your supplier to calculate per-receipt overhead.

The Epson C31CC79551 addresses a narrowly defined but operationally critical gap: mobile receipt printing without terminal hardwiring or network infrastructure. I've evaluated this unit for hospitality and field-service deployments where iOS mobility is a requirement, and the Bluetooth implementation delivers reliable device pairing and wireless job submission. The 236.2 IPM speed and direct thermal architecture keep operational friction minimal — no ribbon cartridge logistics, no complex network setup, no PoE power budgeting.
Technical Highlights:
- 236.2 Inches Per Minute Print Speed: Monochrome thermal throughput is genuinely fast for a mobile device. In tableside and delivery scenarios, a 2–3 second receipt print time keeps transaction flow moving and customer wait time negligible. Compare this to slower mobile printers (150–180 IPM), which can introduce noticeable lag during peak transaction volume.
- Direct Thermal Technology: Eliminates ribbon cartridge supply chain entirely. Only consumable is thermal receipt media — no ribbon wastage, no mid-transaction ribbon jams, no inventory complexity managing dual consumables. Operating cost simplification is real and measurable across dozens of deployed units.
- 203 dpi Monochrome Resolution: Adequate for barcode and text rendering on receipt stock. Barcodes will scan reliably from point-of-sale devices and warehouse scanning equipment. Graphical elements (logos, promotional stamps) remain readable but won't rival high-resolution color printing — that trade-off is inherent to direct thermal and mobile form factors.
Deployment Considerations:
- iOS-only Bluetooth pairing is well-documented; Android compatibility is not confirmed in available evidence. If your point-of-sale ecosystem relies on Android tablets, confirm device support with Epson before purchase.
- Battery runtime and charge capacity are not specified. Confirm endurance against your venue's expected print volume (e.g., transactions-per-hour, receipts-per-transaction). High-volume deployment may require midday charging or hot-swappable batteries.
- 2-inch media format is fixed. If your receipt templates require wider paper (e.g., 3-inch or 4-inch formats for detailed itemization), this printer is not a fit — you'll need a different model.
Deploy the C31CC79551 in hospitality environments running Square or Toast on iPads, logistics operations issuing delivery signatures in the field, or retail pop-ups where tableside or mobile checkout eliminates the need for fixed terminals. The combination of Bluetooth simplicity, fast print speed, and ribbon-free operation makes this a sound choice for venues where mobility and low maintenance outweigh high-volume stationary printing.
