Honeywell PM45-APPL-01 vs Honeywell PX4654-020: Specification Comparison
Both the Honeywell PM45-APPL-01 and the Honeywell 1-PX4654-020 are industrial-class direct thermal and thermal transfer label printers from the same PM45 series. They share the same 4.25-inch maximum print width, Android-based touchscreen interface, and core connectivity suite, making them natural cross-shop candidates for warehouse, manufacturing, and field-deployment label printing applications. This comparison examines where their documented specifications converge and where they diverge to help installers and IT buyers select the right unit.

How do print performance and emulation support compare between the PM45-APPL-01 and the 1-PX4654-020?
Both units are rated for the same maximum print width of 108 mm (4.25 in) and support identical print methods: direct thermal and thermal transfer. Neither unit's specification set discloses print resolution (dpi) or maximum print speed (in/sec), so no comparison on those dimensions is possible from the provided data.
Emulation support is identical across both models: ZPL II, ZSim2, Direct Protocol, Fingerprint, and IPL are listed for each. This means existing label templates and host software configured for any of these languages will operate without modification on either unit, which is a meaningful factor in mixed-fleet or migration scenarios.
Both units run Android as their operating system and feature a 3.5-inch color touch LCD, and both carry 256 MB SDRAM with 512 MB Flash memory. From a pure print-performance and emulation standpoint, the provided specifications show no differentiation between the two models.
Which model offers broader connectivity and integration options for warehouse or facility networks?
The PM45-APPL-01 lists Ethernet, Wi-Fi, and USB as its connectivity interfaces. The 1-PX4654-020 lists Wi-Fi, Ethernet, USB 2.0, and RS-232. The addition of RS-232 on the 1-PX4654-020 is the only interface difference documented in the provided specifications, giving it a legacy serial port that can integrate with older host systems, scales, or PLCs that communicate over serial without requiring an adapter.
Both models specify HTTPS encryption and PoE Class 1 support. The PM45-APPL-01's supplemental spec notes Wi-Fi 802.11ac specifically, while the 1-PX4654-020 does not call out the Wi-Fi standard. Neither unit's spec discloses Bluetooth support, so no comparison is possible there.
For facilities running modern Ethernet-only or wireless-only infrastructure, the connectivity delta is negligible. For sites with legacy serial hosts or serial-connected peripheral devices, the RS-232 port on the 1-PX4654-020 removes an integration barrier that would otherwise require external hardware.
Are there any differences in environmental ratings, physical footprint, or build specs that affect deployment decisions?
Both units share identical physical and environmental specifications across every disclosed dimension. Dimensions are 483 × 295 × 284 mm (19.0 × 11.6 × 11.2 in) and weight is 12.1 kg (26.7 lbs) for both. Operating temperature range is 5 to 40 °C (41 to 104 °F) and storage temperature is -20 to 70 °C (-4 to 152 °F) for both. Humidity tolerance is 10–90% non-condensing on both units.
Neither unit's specification lists an ingress protection (IP) rating, drop resistance, or vibration tolerance, so no comparison on ruggedization level is possible from the provided data. Buyers operating in wash-down, outdoor-exposed, or high-vibration environments should request official environmental certification documentation from Honeywell before finalizing selection.
Because all physical and environmental specifications are identical, rack space planning, mounting hardware, and site thermal management apply equally to both models. There is no footprint or environmental advantage to cite for either unit based on available specs.
Which should you choose: the PM45-APPL-01 or the PX4654-020?
Our take: The 1-PX4654-020 is the stronger choice when the installation site includes legacy serial hosts, scales, or peripherals that communicate over RS-232, since it is the only model in this comparison documented to carry that interface. On every other disclosed specification—108 mm print width, 256 MB SDRAM / 512 MB Flash, 3.5-inch color touch LCD, Android OS, ZPL II / ZSim2 / Direct Protocol / Fingerprint / IPL emulations, HTTPS encryption, PoE Class 1, 12.1 kg weight, 483 × 295 × 284 mm footprint, and 5–40 °C operating range—the two units are spec-for-spec identical. The PM45-APPL-01's supplemental data explicitly names Wi-Fi 802.11ac, while the 1-PX4654-020 does not specify the Wi-Fi standard; if AC-band throughput is a validated site requirement, that warrants direct confirmation with Honeywell. For purely modern Ethernet and Wi-Fi environments, either unit satisfies the same requirement set.

Frequently Asked Questions
Which should you choose: the PM45-APPL-01 or the PX4654-020?
The 1-PX4654-020 is the stronger choice when the installation site includes legacy serial hosts, scales, or peripherals that communicate over RS-232, since it is the only model in this comparison documented to carry that interface. On every other disclosed specification—108 mm print width, 256 MB SDRAM / 512 MB Flash, 3.5-inch color touch LCD, Android OS, ZPL II / ZSim2 / Direct Protocol / Fingerprint / IPL emulations, HTTPS encryption, PoE Class 1, 12.1 kg weight, 483 × 295 × 284 mm footprint, and 5–40 °C operating range—the two units are spec-for-spec identical. The PM45-APPL-01's supplemental data explicitly names Wi-Fi 802.11ac, while the 1-PX4654-020 does not specify the Wi-Fi standard; if AC-band throughput is a validated site requirement, that warrants direct confirmation with Honeywell. For purely modern Ethernet and Wi-Fi environments, either unit satisfies the same requirement set.
Is the PM45-APPL-01 or the 1-PX4654-020 better for connecting to an older host system over a serial port?
Based on the provided specifications, the 1-PX4654-020 is the documented choice for serial connectivity. It lists RS-232 as a supported interface; the PM45-APPL-01 does not include RS-232 in its specification set. If legacy serial integration is required, the 1-PX4654-020 avoids the need for an external serial adapter or converter.
Can both printers handle the same label formats and host software emulations?
Yes, based on the provided specifications. Both models list identical emulation support: ZPL II, ZSim2, Direct Protocol, Fingerprint, and IPL. Existing label templates or host software written for any of these languages should operate on either unit without modification.
Do these two printers have any differences in size, weight, or operating environment that would affect where I can install them?
No differences are documented in the provided specifications. Both units share the same dimensions (483 × 295 × 284 mm), weight (12.1 kg), operating temperature range (5–40 °C), storage temperature range (-20 to 70 °C), and humidity tolerance (10–90% non-condensing). Neither spec includes an IP ingress-protection rating, so wash-down or outdoor suitability cannot be confirmed from available data alone.
