Product Description

The Citizen CL-S400DT is designed for businesses that require flexible direct thermal printing without moving to a larger industrial printer.

Its compact desktop footprint makes it suitable for counters, ticketing desks, offices, warehouses and operational workstations where space is limited.

The printer can handle both roll and fanfold media, making it particularly useful for applications where conventional adhesive labels and thicker ticket or tag media may both be required.

Citizen’s Hi-Lift™ metal mechanism provides wide access to the media path, while the Hi-Open™ case opens vertically to reduce the additional workspace required when accessing the printer.

Direct Thermal Printing

The CL-S400DT uses direct thermal printing technology.

This means the printhead creates the image directly on compatible heat-sensitive media.

No thermal-transfer ribbon is required.

This makes the printer suitable for applications where direct thermal media provides the required label or ticket lifespan.

For applications requiring long-term resistance to heat, sunlight, chemicals or other demanding environmental conditions, confirm whether direct thermal media is appropriate before selecting this printer.

Print Resolution

Resolution: 203 dpi

203 dpi is widely used for general-purpose barcode and label printing and is suitable for applications such as:

• Product labels
• Shipping and logistics labels
• Tickets
• Retail labels
• Identification labels
• Barcode labels
• Shelf labels
• Event tickets
• Visitor tickets
• Tags

Very small text, extremely dense barcodes or specialized high-resolution applications may require a higher-resolution printer.

Print Width

Maximum Print Width: 104 mm / 4 inches

This provides flexibility for many common desktop labeling and ticketing formats.

The actual printable area depends on the selected media dimensions, printer configuration and label design.

Media Support

The CL-S400DT supports compatible:

• Roll media
• Fanfold media
• Die-cut labels
• Continuous media
• Perforated media
• Tags
• Tickets
• Thermal labels

Media Width: Approximately 12.5–118 mm

Media Thickness: Approximately 63.5–254 µm

Media Length: Approximately 6.35–812.8 mm

The correct media type, dimensions and thermal characteristics should be verified for the intended application.

Media Detection

The CL-S400DT provides adjustable media sensing for:

• Gap media
• Notched media
• Reflective black-mark media

Correct sensor configuration is important for accurate label positioning and reliable media handling.

Connectivity

Standard Interfaces

• USB 2.0
• RS-232C Serial

Optional Connectivity

Depending on the installed configuration, interface options can include:

• Ethernet
• Parallel
• Wireless LAN

Optional interfaces should not be assumed to be installed unless specifically stated for the unit being quoted.

Printer Languages and Emulation

The CL-S400DT supports several printer command environments, including:

• Zebra® ZPL2®
• Eltron® EPL2®
• Datamax® DMX
• Citizen Cross-Emulation™

This can help when integrating the printer into existing label-printing environments.

Software compatibility should still be verified with the exact application, driver and operating system before deployment.

CL-S400DT vs Thermal Transfer Printer

The CL-S400DT should not be confused with Citizen models that support both direct thermal and thermal transfer printing.

The CL-S400DT is a direct thermal printer.

Choose the CL-S400DT when:

• Ribbon-free printing is preferred
• Direct thermal media is appropriate
• Ticket or tag printing is required
• Roll and/or fanfold media is needed
• 203 dpi is suitable
• A compact desktop printer is preferred

If your labels require thermal-transfer ribbons for longer-term durability, chemical resistance or demanding environmental exposure, consider an appropriate thermal-transfer printer instead.

CL-S400DT vs CL-S400DTII

The CL-S400DT and CL-S400DTII are separate Citizen models.

When replacing an existing printer or ordering accessories, interfaces or spare parts, verify the exact model printed on the equipment.

Do not assume that every specification, accessory or component is interchangeable between the CL-S400DT and CL-S400DTII.

Software and Operating-System Compatibility

Citizen provides drivers and printer-support software for its label-printer range.

Compatibility depends on:

• Operating system
• Driver version
• Label-design software
• Application
• Printer language
• Interface
• System configuration

If the printer will be integrated with a specific POS, ERP, warehouse, ticketing or label-management system, confirm compatibility before ordering.
