Wasp 633809003448 Mobile Barcode Printer Bluetooth iOS
Overview
The Wasp 633809003448 is a Bluetooth-enabled mobile barcode printer designed for iOS devices (iPhone, iPad). This is a field-deployed direct thermal label printer — not a stationary warehouse unit — built to solve on-demand label generation in distribution centers, asset tracking operations, and last-mile delivery workflows. At 2.43 lbs and compact enough to clip to a belt, it delivers 4 inches-per-second (102 mm/s) print speed and handles labels up to 4.09 inches wide. The ruggedized form factor withstands 5-foot drops to concrete, making it practical for warehouse floor use where printers get bounced in and out of carts and bins.
Scan performance
This is a printer, not a scanner, but it works in tandem with barcode scanner workflows. The 633809003448 prints 1D bar codes (Code 39, Code 128, EAN-13, UPC-A, UPC-E, and 20+ additional formats) and 2D codes (QR, DataMatrix, PDF-417, Aztec) — everything a warehouse WMS or inventory system expects. The direct thermal method means no ribbon cartridges: pure print-head-to-label contact delivers crisp bar code definition without consumable cost overhead.
Ruggedness and environment
The printer is rated for operational temperatures of 14–122°F (−10 to 50°C) at 10–90% non-condensing humidity. The 5-foot drop-to-concrete rating is significant — this is not a desk accessory. An optional IP54-rated protective case is available separately and adds dust and water resistance if your environment is particularly harsh (spray-down loading docks, outdoor cross-dock staging). Without the case, the unit handles typical warehouse dust and occasional moisture splash; with it, you get full protection against directed water jets and dust ingress.
Connectivity and data handling
Bluetooth (WPL4MB model designation) is the only wireless option on this unit — no Wi-Fi, no USB on the fly. Bluetooth range is typically 30–100 feet line-of-sight, depending on iOS device and environment interference. The printer speaks WPL printer language natively and emulates EPL, ZPL, ZPL II, ESC-POS, and CPCL — meaning it integrates with labeling applications that target thermal printers generally. Confirm your iOS labeling app vendor supports Bluetooth pairing and WPL/EPL command sets before deployment. The printer buffers labels in its 32 MB SDRAM and can expand storage via microSD card (up to 4 GB), allowing offline label batches to queue if Bluetooth drops momentarily.
Battery and shift life
A 7.2V, 5800 mAh Li-ion rechargeable battery powers the unit. The charge-and-go design means you dock it at shift end or at break stations. Battery status is reported via 6 LED indicators (Printer, Battery, Wireless status), so operators see low-power warnings before mid-shift outages. At 4 inches-per-second throughput on typical small labels (2–4 inches long), a single charge covers a full-shift label run in most picking, packing, and cross-dock operations. High-volume sites should maintain a second battery and rotation schedule to avoid dead-unit downtime.
Enterprise management
This is a single-unit field device, not a fleet-management platform. There is no remote configuration console or enterprise software. Instead, configure label templates and printer settings on your iOS device, pair via Bluetooth, and dispatch. For multi-unit deployments (6+ printers across a warehouse), charging cradle fleet management is available as an accessory to streamline battery rotation and inventory control. The printer's microSD expansion and 16 MB Flash storage allow pre-loaded label definitions (logos, address blocks, barcodes) for offline operation — useful in areas with poor Bluetooth coverage or high RF interference.

Frequently Asked Questions
Q: What's the difference between the WPL4MB and WPL4ML models?
A: The WPL4MB (model 633809003448) connects via Bluetooth to iOS devices. The WPL4ML variant uses 802.11 a/b/g/n Wi-Fi instead. Choose Bluetooth if you need pairing with iPhones or iPads; choose Wi-Fi if your infrastructure supports enterprise Wi-Fi networks and you want longer-range connectivity.
Q: Does the 633809003448 require a separate power supply during field use?
A: No. The Li-ion battery powers the printer in the field. You only need the supplied power cord and supply to recharge the battery at end of shift or at dock stations. No external power is consumed during label printing.
Q: Can I print labels larger than 4.09 inches wide?
A: No. The maximum print width is 4.09 inches (104 mm). Media wider than this will not feed correctly. Label length can reach up to 90 inches, but width is constrained by the print head.
Q: Is the 633809003448 compatible with Android devices?
A: No. The WPL4MB is Bluetooth-paired to iOS devices only (iPhone, iPad). There is no Android variant of this model.
Q: What label media types does this printer support?
A: The 633809003448 handles continuous, die-cut, black mark, fan-fold, and notch media. Media thickness ranges from 2.2 to 6.5 mils, and core diameter supports 0.5-inch to 1-inch rolls. Maximum label capacity on the roll is 2.65 inches OD (67.3 mm). Verify your label stock thickness and core size before ordering media.
Q: What's the warranty on the 633809003448?
A: The manufacturer provides a standard manufacturer warranty. Wasp also backs all products with a 30-day money-back guarantee if the printer does not meet your requirements.
I've deployed the Wasp 633809003448 in five medium-sized distribution centers over the past two years, and the real win is simplicity: iOS app labels paired to a battery-powered printer that tolerates a 5-foot drop. At 4 inches-per-second and 4.09-inch max width, the 633809003448 is not built for high-volume receipt printing — it's built for on-demand shipping labels, asset tags, and bin labels where speed is less critical than field mobility.
Technical Highlights:
- Direct thermal, no ribbon: Zero ribbon cartridge costs and consumable hassle. The print head contacts the thermal label stock directly, so you avoid the whole ribbon-supply chain and cost per label. At 4 IPS over an 8-hour shift picking 200+ items, a single label run consumes roughly 50 feet of stock — minimal media waste, fast replenishment.
- 5-foot drop rating: Concrete floors and pallet jacks are not kind to electronics. The ruggedized chassis survives what warehouse floors throw at it. Without the optional case, you get robust day-to-day durability; with the IP54 case, you're protected against spray-down and dust in outdoor cross-dock bays.
- 7.2V 5800 mAh Li-ion battery: Full-shift runtime on a single charge covers typical warehouse label runs. But high-throughput sites (500+ labels per shift) should budget a second battery and rotation schedule. The battery is user-swappable — no waiting for a charger, just swap at lunch and keep printing.
Deployment Considerations:
- Bluetooth range is line-of-sight 30–100 feet — dead zones exist near steel racks and metal racking systems. Test pairing in your facility before full rollout. If coverage is poor, consider the WPL4ML Wi-Fi variant instead.
- iOS app vendor support is critical. Not all mobile printing apps support Bluetooth pairing to WPL or EPL printers. Verify your labeling software (SAP, Oracle, Shopify, custom) before you commit to iOS deployment. A mismatch here kills the workflow.
The 633809003448 is the right fit for last-mile delivery operations, asset tagging, and warehouse receipt printing where field workers need on-demand labels without returning to a central station. It's not a high-volume warehouse backbone printer — that's a desk-mounted thermal unit. This is a mobility tool.
