Rugged 4-Inch Mobile Printing

The RJ-4255WB is designed for applications requiring larger mobile documents than conventional 2-inch or 3-inch portable printers.

Its maximum print width is:

104 mm

This makes the printer suitable for compatible 4-inch-class media and mobile applications requiring more information per label or receipt.

Potential uses include:

• Shipping labels
• Delivery documentation
• Warehouse labels
• Inventory labels
• Product labels
• Mobile receipts
• Service documentation
• Transportation labels
• Field identification labels

Direct Thermal Printing

The RJ-4255WB uses:

Direct Thermal Printing

This means compatible heat-sensitive media is printed without requiring:

• Ink
• Toner
• Thermal-transfer ribbon

Direct thermal technology can simplify consumables management for mobile printing operations.

Compatible direct thermal media is required.

203 dpi Print Resolution

The RJ-4255WB provides:

203 dpi

This is suitable for many mobile label and receipt applications involving:

• Text
• Numbers
• Barcodes
• QR Codes
• Graphics
• Product information
• Shipping information
• Tracking references

Print quality and barcode readability depend on factors including media quality, print settings, barcode size and operating conditions.

Up to 127 mm/s Print Speed

Brother specifies maximum printing speed of:

Up to 127 mm/s / 5 ips

for standard supported printing conditions.

This can help mobile workers produce labels and receipts efficiently without returning to a stationary desktop printer.

When using Brother's optional linerless configuration, maximum speed is lower than the standard configuration.

Media Width

The RJ-4255WB supports media widths from:

45 mm to 114 mm

This allows the printer to accommodate different mobile printing requirements.

Maximum Print Width

Maximum Print Width: 104 mm

The media itself can be wider than the maximum printable image area.

Supported Media Types

Brother specifies support for media including:

• Receipt media
• Gap labels
• Black-mark labels
• Tags
• Linerless media with the appropriate optional configuration

The correct media should be selected according to the printer configuration and intended application.

Media Specifications

Media Width: 45–114 mm
Maximum Roll Outside Diameter: 58 mm
Receipt Thickness: Approximately 0.058–0.090 mm
Tag Thickness: Approximately 0.090–0.135 mm
Label Thickness: Approximately 0.080–0.170 mm
Media Sensors: Transmissive and Reflective

Media performance can vary by material, adhesive, coating and environmental conditions.

For business-critical label applications, the selected media should be tested with the printer before volume deployment.

Wi-Fi Connectivity

The RJ-4255WB provides wireless LAN connectivity for compatible networked mobile printing applications.

Wi-Fi can be useful where workers need to print through a business wireless network without physically connecting the printer to the host device.

Potential environments include:

• Warehouses
• Distribution centres
• Retail operations
• Logistics facilities
• Hospitals and healthcare operations
• Field-service locations

Wireless compatibility and security requirements should be checked against the intended network environment.

Bluetooth Connectivity

The RJ-4255WB also provides Bluetooth connectivity for compatible host devices.

This can support direct mobile printing workflows involving suitable:

• Handheld computers
• Tablets
• Smartphones
• Mobile terminals
• Business devices

Compatibility depends on the host hardware, operating system, application and required Bluetooth profile.

USB Type-C

The RJ-4255WB supports USB Type-C connectivity.

USB-C can be used for applicable data and charging workflows.

Brother specifies approximate charging times under its stated test conditions of:

• Approximately 3 hours using the appropriate AC adapter
• Approximately 3 hours using USB Type-C to Type-C
• Approximately 9 hours using USB Type-C to Type-A

Actual charging time can vary with battery condition, power source, temperature and usage.

Rechargeable Battery Operation

The RJ-4255WB is designed around a rechargeable lithium-ion battery system for mobile operation.

Brother specifies:

Rechargeable Li-ion Battery: 7.2V

For the RJ-4235B / RJ-4255WB platform, Brother's test specification references up to approximately 10,000 labels per charge under defined test conditions with a new, fully charged battery.

This should not be treated as a guaranteed real-world number.

Actual battery runtime depends on:

• Print coverage
• Number of labels
• Wireless usage
• Print frequency
• Environmental temperature
• Battery age
• Media
• Printer settings
• Charging history

Rugged Design

The RuggedJet RJ-4255WB is specifically designed for mobile business environments where equipment may experience more physical stress than a conventional desktop printer.

Brother specifies:

IP54 Rated

MIL-STD-810G Vibration/Shock

Multiple-Drop Protection: Up to 2.1 m

The drop specification is based on multiple drops onto concrete under Brother's controlled test conditions.

These ratings should not be interpreted as meaning the printer is indestructible, waterproof or protected from every type of impact.

IP54 Protection

The RJ-4255WB carries an IP54 rating.

This provides defined protection against dust ingress and splashing water under the applicable rating conditions.

It does not mean the printer is waterproof or suitable for immersion.

2.1 Metre Drop Protection

Brother specifies multiple-drop protection from:

Up to 2.1 metres

for the RJ-4235B / RJ-4255WB platform under controlled test conditions.

This ruggedness can be valuable for workers who carry printers throughout warehouse, delivery and field environments.

Maximum Print Length

Brother specifies:

Continuous Media: Up to 3,000 mm

Die-Cut / Black-Mark Media: Up to 1,000 mm

Actual document design and application support should be considered when using extended print lengths.

Printer Dimensions

Approximate dimensions:

153 mm (W) × 68 mm (H) × 159 mm (D)

Printer Weight

Approximate weight including rechargeable Li-ion battery:

850 g

The relatively compact body allows the printer to remain portable while accommodating media up to the 4-inch class.

Linerless printing can be useful for workflows where reducing backing-liner waste is desirable.

Brother specifies a maximum printing speed of approximately:

76.2 mm/s / 3 ips

when using the linerless platen configuration.

The linerless platen is an optional configuration and should not be assumed to be installed as standard.

A label-peeler option is available for applicable deployments.

The peeler can help present individual labels for quicker removal during repetitive labeling tasks.

This can be useful in:

• Warehousing
• Inventory
• Shipping
• Retail
• Field labeling

The peeler is optional and should not be assumed to be included with the standard printer.

Power & Charging Options

Depending on deployment requirements, Brother provides power and charging options for the RuggedJet platform.

These can include:

• Rechargeable Li-ion battery
• USB-C charging
• Optional AC adapter
• Optional vehicle/car adapter

• Maintenance labels
• Customer documentation

Retail

In suitable retail environments, mobile printing can support:

• Shelf labels
• Markdown labels
• Price labels
• Inventory labels
• Mobile receipts
• Stockroom operations

Purpose of Use

The Brother RJ-4255WB is particularly relevant when the requirement includes:

• 4-inch mobile printing
• Rugged portable construction
• Wi-Fi
• Bluetooth
• USB-C
• 203 dpi printing
• Up to 127 mm/s print speed
• Labels and receipts
• IP54 protection
• Mobile battery operation
• Warehouse or field use

RJ-4255WB vs RJ-4235B

The RJ-4255WB and RJ-4235B share the same 4-inch RuggedJet platform and core print characteristics.

The RJ-4255WB is the more appropriate choice where wireless LAN/network capability is required in addition to Bluetooth and USB connectivity.

The exact connectivity requirement should therefore be established before selecting between RuggedJet models.
