Linerless Label Printing

The MCL21CI is equipped with a linerless platen for printing on compatible linerless adhesive label media.

Linerless labels do not use a conventional disposable backing liner. This can reduce backing-paper waste compared with equivalent lined label applications.

Potential benefits include:

• Reduced Label Liner Waste
• Convenient On-Demand Label Printing
• Flexible Label Lengths Within Supported Limits
• Simplified Label Handling
• Reduced Disposal of Backing Material

Linerless media must be specifically approved for the printer and cutter mechanism.

Not every adhesive label roll is compatible with linerless printing.

Automatic Cutter

The MCL21CI includes an automatic cutter.

The cutter supports compatible label and receipt separation according to the printer's media and software configuration.

Actual cutting functionality depends on:

• Media Type
• Label Dimensions
• Adhesive Construction
• Printer Settings
• Software Commands
• Manufacturer Compatibility Requirements

Customers should not assume that every thermal label or adhesive material can be safely cut.

Retail Applications

The MCL21CI may be suitable for compatible retail labeling operations, including:

• Product Identification Labels
• Stockroom Labels
• Inventory Labels
• Order Identification
• Shelf and Storage Labels
• Internal Goods Tracking

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

Hospitality and Food Service Applications

The mC-Label2 range is suitable for consideration in compact hospitality and food service environments.

Potential applications include:

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

Food safety requirements, adhesive suitability, temperature resistance and any required regulatory compliance depend on the selected media and application.

The printer itself should not be described as food-contact certified without supporting documentation.

Warehouse and Inventory Applications

The MCL21CI may support compatible internal labeling requirements such as:

• Inventory Identification
• Warehouse Bin Labels
• Stock Movement Labels
• Equipment Identification
• Internal Logistics Labels
• Asset Tracking

For larger shipping labels, industrial environments or specialized materials, another printer may be more appropriate.

300 dpi Direct Thermal Printing

The MCL21CI uses direct thermal technology.

The printer applies heat to compatible thermal media to produce text, graphics and barcodes.

This method does not require ink, toner or thermal transfer ribbons.

The 300 dpi resolution supports detailed printing within the printer's specified printable width.

Direct thermal print durability depends on the selected 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 performance may vary depending on label length, print density, graphics, software, media and operating conditions.

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

Media Width and Roll Capacity

Supported Media Width: 25–60 mm
Effective Print Width: Approximately 15–56.9 mm
Maximum Roll Diameter: 102 mm

Customers should confirm:

• Label Width
• Required Label Length
• Media Roll Diameter
• Roll Core Dimensions
• Adhesive Type
• Thermal Coating
• Cutter Compatibility
• Linerless Media Approval

Media width and printable width are different measurements.

Ethernet Network Connectivity

The MCL21CI includes Ethernet connectivity for compatible wired network printing.

This may support integration with network-connected business systems, subject to the required software and communication protocols.

Customers should confirm their network and application requirements before ordering.

USB-C Connectivity

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

The actual capabilities depend on the connected device, cable and supported power configuration.

USB-C connectivity does not guarantee universal compatibility with every tablet, POS terminal or computer.

CloudPRNT and CloudPRNT Next

The MCL21CI supports Star Micronics CloudPRNT technologies.

These technologies allow compatible cloud applications to communicate with supported printers through an appropriately configured network.

CloudPRNT integration requires suitable application support, network configuration and technical verification.

Custom cloud application development is not included in standard hardware supply.

Software and Operating System Compatibility

Star Micronics provides software and development resources for supported environments, including:

• Windows
• macOS
• Linux
• Android
• iOS

Relevant technologies may include StarPRNT, StarXpand SDK, CloudPRNT and compatible setup utilities.

The exact supported functions depend on the printer model, firmware, connection method and application.

Customers should verify their software compatibility before purchasing.

Compact Front-Loading Design

The printer measures approximately:

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

Its compact design is suitable for installations where counter space is limited.

Front-loading media access helps simplify roll replacement.

Adequate space should be maintained for ventilation, cables and routine operation.

IP22 Protection Rating

The MCL21CI has an IP22-rated housing.

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

It does not mean the printer is waterproof or washable.

The printer should be installed and maintained according to the manufacturer's instructions.
