Specifications refer to the MCL21CWBI X4 configuration. Actual performance, media compatibility, software functionality, accessories and warranty depend on the supplied product and operating conditions.

Linerless Label Printing

The MCL21CWBI X4 is equipped with a linerless-compatible platen and automatic cutter.

Linerless labels do not use the conventional disposable backing liner found on many self-adhesive labels.

With approved media, this can reduce discarded backing material and support convenient on-demand label printing.

Potential applications include:

• Food Preparation Labels
• Order Identification Labels
• Product Information Labels
• Stock Identification
• Kitchen Production Labels
• Inventory Tracking
• Hospitality Labels
• Internal Logistics Labels

The printer supports compatible permanent and repositionable linerless label media.

Important: Linerless compatibility does not mean that every adhesive thermal roll can be used. Customers should verify media approval, adhesive properties, dimensions and cutter compatibility before purchasing.

Automatic Cutter

The MCL21CWBI X4 includes a guillotine-style automatic cutter.

The cutter supports compatible full and partial cutting operations, depending on the selected media and application.

Potential advantages include:

• Automated Label Separation
• Consistent Cutting
• Reduced Manual Handling
• Convenient On-Demand Label Output
• Support for Compatible Variable-Length Labels

Cutter performance depends on the media construction, adhesive, printer settings and software commands.

Unsupported adhesive materials may affect printing and cutting reliability.

Wi-Fi Wireless Printing

The MCL21CWBI X4 includes built-in WLAN connectivity.

This allows the printer to communicate with compatible applications over a supported wireless network.

Potential uses include:

• Wireless Retail Label Printing
• Hospitality Label Printing
• Networked Kitchen Workflows
• Mobile Inventory Applications
• Compatible Cloud-Based Printing

Wireless operation requires appropriate network configuration and supported application software.

Network security and access settings should be managed according to the customer's IT requirements.

Bluetooth Connectivity

The MCL21CWBI X4 includes MFi-certified Bluetooth connectivity.

Bluetooth can support compatible printing workflows using supported mobile devices and applications.

Actual functionality depends on:

• Device Operating System
• Bluetooth Connection Method
• Application Compatibility
• Printer Firmware
• Required Printer Commands

MFi certification does not guarantee compatibility with every iOS application.

Ethernet LAN Connectivity

The printer includes Ethernet LAN for compatible wired network printing.

This can be useful where a fixed network connection is preferred for business operations.

Ethernet connectivity does not automatically establish compatibility with every POS or inventory management platform.

Customers should confirm the application and network requirements before ordering.

USB-C with Power Delivery

The MCL21CWBI X4 includes USB-C connectivity with supported Power Delivery functionality.

Compatible host devices may benefit from simplified communication and power arrangements.

The actual functionality depends on the host device, cable, software and supported power configuration.

SteadyLAN Technology

Star SteadyLAN supports compatible network communication arrangements involving USB-C-connected devices.

This may be useful in supported POS and tablet-based business environments.

Compatibility depends on the connected hardware, operating system, network configuration and Star software implementation.

CloudPRNT and CloudPRNT Next

The MCL21CWBI X4 supports Star CloudPRNT technologies.

These enable compatible applications to communicate with supported printers through cloud-based printing workflows.

Potential applications include:

• Cloud-Based Retail Label Printing
• Hospitality Order Labels
• Kitchen Production Labels
• Web-Based Inventory Applications
• Connected Business Workflows

CloudPRNT requires compatible software, network access and appropriate configuration.

Custom cloud application development and integration are not included in standard hardware supply.

300 dpi Direct Thermal Printing

The printer uses direct thermal technology.

Text, barcodes and graphics are produced by applying heat to compatible thermal media.

No ink cartridges, toner or thermal transfer ribbons are required.

The 300 dpi printhead is suitable for many detailed business labeling applications within the supported print width.

Direct thermal print durability depends on the media and exposure to heat, sunlight, abrasion and chemicals.

Maximum Print Speed – 180 mm/s

Star Micronics specifies a maximum print speed of 180 mm/s.

Actual printing speed depends on:

• Label Dimensions
• Media Type
• Print Density
• Barcode and Graphic Content
• Software Configuration
• Communication Method
• Printer Operating Conditions

The maximum rated speed should not be interpreted as a guaranteed production rate.

Media Compatibility

The MCL21CWBI X4 supports several types of manufacturer-approved thermal media.

These include:

• Permanent Linerless Labels
• Repositionable Linerless Labels
• Traditional Liner-Backed Die-Cut Labels
• Continuous Thermal Labels
• Thermal Receipt Paper

Supported Media Width: 25–60 mm
Effective Print Width: 15–56.9 mm
Maximum Roll Diameter: 102 mm
Media Thickness: 53–154 µm, depending on media

Before ordering consumables, customers should confirm:

• Label Width and Length
• Roll Diameter
• Roll Core Dimensions
• Adhesive Type
• Thermal Coating
• Media Thickness
• Sensor Requirements
• Cutter Compatibility
• Required Print Durability

Not all media types are suitable for every business application.

Print Hold and Paper Taken Sensor

The printer includes a paper-taken detection function.

This can support compatible workflows where a printed label is presented for collection before the next label is produced.

Actual operation depends on the printer settings, media type and application.

One-Touch-Label Function

The mC-Label2 range includes Star's One-Touch-Label functionality.

This allows up to three compatible static label designs to be stored for convenient repeat printing.

The feature may be useful for frequently repeated labeling tasks.

Initial label design and configuration require the appropriate Star software and setup procedure.

Retail Applications

The MCL21CWBI X4 may be suitable for compatible retail applications, including:

• Product Identification Labels
• Barcode Labels
• Shelf Identification
• Inventory Labels
• Stockroom Labels
• Order Identification
• Retail Preparation Labels

Compatibility with an existing POS or inventory application must be verified before purchasing.

Hospitality and Food Service Applications

The printer may support compatible hospitality and food preparation labeling requirements.

Potential uses include:

• Food Preparation Identification
• Takeaway Order Labels
• Kitchen Production Labels
• Ingredient Identification
• Date and Time Labels
• Order Tracking
• Internal Food Storage Labels

Customers should select media appropriate for the required temperature, adhesive performance and food safety environment.

No food-contact certification is implied without supporting documentation.

Warehouse and Inventory Applications

The MCL21CWBI X4 may be used for compatible warehouse and inventory labeling tasks, including:

• Inventory Identification
• Warehouse Location Labels
• Asset Labels
• Stock Movement Labels
• Equipment Identification
• Internal Logistics Labels

The printer's maximum effective print width is approximately 56.9 mm.

It is not intended for conventional 4-inch-wide shipping labels.

Actual compatibility depends on the selected application, operating system, printer firmware and connection method.

The existence of software development resources does not guarantee automatic compatibility with every business application.

Compact Front-Loading Design

The MCL21CWBI X4 measures approximately:

Width: 98 mm
Depth: 185 mm
Height: 145.5 mm
Weight: 1.6 kg

Its compact housing is designed for environments where counter space is limited.

The front-loading media arrangement provides convenient access for replacing rolls.

Suitable clearance should be maintained for cables, ventilation and printer operation.

IP22 Protection Rating

The MCL21CWBI X4 has an IP22-rated housing.

IP22 provides limited protection against specified solid objects and dripping water under defined test conditions.

The printer is not waterproof and should not be washed or exposed to uncontrolled moisture.

Installation and maintenance should follow the manufacturer's instructions.
