The PX45 is Honeywell's 4-inch industrial model, positioned as a smart printing platform. Beyond printing labels, it leaves room for custom logic: C# and Fingerprint programming can run business rules inside the printer.
The 406 dpi tier
Resolution comes in 203, 300 and 406 dpi. The 406 option is unusual, sitting between 300 and 600 for work that needs more precision than 300 dpi but not the extremes of 600. Small 2D codes and dense text often land exactly there.
Speed runs 100 to 300 mm/s. A dual-core 1 GHz processor with 256 MB of memory and 512 MB of flash keeps large labels and complex formats from stalling.
What in-printer logic is worth
Some line logic does not belong on a server. Scan a code, decide which label a workpiece needs, print it. Routing that through a server adds a network hop and another failure point.
The PX45 can run that logic internally: connect a scanner, and the decision and the print happen in one device. This pattern appears on automated lines, though it takes development effort and design work up front rather than working out of the box.
Interfaces and expansion
Connectivity is thorough: USB 2.0 host and device, 10/100 Ethernet, RS-232, parallel IEEE1284, and industrial 8-channel digital I/O. Digital I/O is the key to line integration, reading and writing external signals directly.
Wi-Fi 802.11 a/b/g/n/ac and Bluetooth are optional, as is an RFID module for UHF tag writing. Media rolls go up to 213 mm OD, ribbon up to 450 m.
PX45 or PX65
Follow the label width. Up to 4 inches (108 mm), the PX45 gives you 406 dpi. For 6-inch wide labels with multi-column layouts, the PX65 goes wider but tops out at 300 dpi. Width and precision usually trade against each other.
