Wasp 633809003424 Mobile Barcode Printer Wi-Fi

Overview

The Wasp 633809003424 (WPL4ML) is a portable direct thermal barcode printer built for on-demand label printing away from a fixed workstation. At 4 inches per second (102 mm/s) print speed and 203 dpi resolution, it handles standard 1D and 2D barcode labels in real time — the critical piece for warehouse receiving, cross-dock operations, and mobile inventory workflows where you generate and apply labels without returning to a desk. Wi-Fi connectivity (802.11 a/b/g/n) eliminates USB tether dependency, allowing print jobs from mobile devices or handheld computers over your wireless network. The rechargeable 5800 mAh lithium-ion battery provides sustained shift-length operation without external power connections.

Compatibility

The WPL4ML integrates with any WMS, inventory management system, or mobile application that supports standard thermal printer protocols over IP-based wireless networks. It accepts print jobs via standard ESC/POS-compatible command sets and WPL firmware language, making integration straightforward with most enterprise label design and batch printing tools. Confirm your WMS or mobile app platform supports wireless printer discovery and TCP/IP print queue assignment — some legacy systems require manual IP address assignment rather than automatic device detection. The printer works with any 2.4 GHz or 5 GHz wireless network; if your facility uses band-specific APs, verify the router or access point supports the frequency your deployment needs.

Installation Notes

Initial setup requires connection to your site's wireless network and assignment of network credentials via the printer's setup interface — typically handled through a mobile app or web configuration page. Assign a static IP address for consistent print queue routing and avoid re-discovery delays during shift operation. The built-in gap and black-mark sensors require label stock with either transparent gaps or dark band registration marks — standard for thermal printer roll stock. Battery charging uses a standard wall outlet; no separate power supply is needed if operating entirely on battery. For multi-printer deployments across a single access point, confirm your network bandwidth can sustain sustained data bursts during batch label printing, as thermal printers generate concentrated traffic during high-volume label runs.
