The Microplex SOLID 45ET is a high-performance industrial tractor-fed thermal printer designed for continuous label and document printing in demanding production and logistics environments. Unlike conventional roll-fed label printers, the SOLID 45ET is engineered to handle continuous fanfold media and tractor-fed forms, making it ideal for applications where large volumes of labels, tags or documents must be printed reliably without interruption.
With its wide 8-inch print capability, the SOLID 45ET can produce labels and documents up to DIN A4 size, allowing organisations to generate shipping labels, industrial tags and production documentation quickly and efficiently. The printer is built for high-speed continuous operation, delivering the first printed page in just two seconds and supporting print speeds of up to 45 pages per minute.
Designed for integration into enterprise and industrial environments, the SOLID 45ET supports multiple printer languages and is compatible with systems such as SAP and IBM AS/400. This allows organisations to deploy the printer within existing production and logistics systems without requiring major changes to their software infrastructure.
Microplex SOLID 45ET Industrial Tractor Thermal Printer
Designed for Continuous Industrial Printing
The Microplex SOLID 45ET is engineered for environments where printers must operate continuously as part of production, logistics or document processing workflows. Its tractor-fed media system allows it to process continuous forms and fanfold labels reliably, making it particularly suitable for high-volume industrial printing applications.
Unlike roll-based label printers, the tractor mechanism ensures precise paper handling and consistent alignment, even when printing large batches of labels or documents over long periods of operation.

Typical Applications
The Microplex SOLID 45ET is designed for environments where continuous forms, fanfold labels and large format documents must be printed reliably as part of operational workflows. Its tractor-fed media system and high-speed printing make it particularly suitable for specialised industrial and logistics applications.
Typical technical applications include:
• Continuous fanfold label printing used in logistics and warehouse systems
• Large pallet and shipping documentation printed alongside barcode labels
• Production documentation printing within manufacturing environments
• Automated printing within packaging and sorting systems
• Top sheet printing in newspaper and publishing production
• Continuous logistics documentation for dispatch and goods tracking
• Industrial tag and form printing on tractor-fed media
• Batch printing of warehouse and distribution documentation
Because the printer supports continuous fanfold media and tractor-fed forms, it is often deployed in environments where traditional roll-fed label printers are not suitable for the workflow.
What is Tractor Thermal Printing
Tractor thermal printing is a method of printing that uses a tractor feed mechanism to move continuous paper or fanfold labels through the printer. The paper contains small perforated holes along the edges which are engaged by tractor wheels inside the printer. This ensures that the paper advances with extremely precise alignment during printing.
Unlike roll-fed label printers, tractor-fed printers are designed to handle continuous forms and long print runs without interruption. This makes tractor thermal printers particularly suitable for industrial environments where large volumes of labels, tags or documentation must be printed reliably and consistently.
Because the paper path is mechanically controlled by the tractor system, tractor thermal printers are often used in applications such as:
• continuous logistics documentation
• fanfold shipping labels
• production and warehouse documentation
• industrial tags and forms
• high-volume batch printing
The Microplex SOLID 45ET uses this tractor-fed printing system to provide reliable continuous printing for demanding production and logistics workflows.
Frequently Asked Questions – Microplex SOLID 45ET
What is the Microplex SOLID 45ET used for?
The Microplex SOLID 45ET is designed for environments where continuous forms, fanfold labels and large format documents must be printed reliably as part of production or logistics workflows.
Typical applications include:
• Continuous fanfold shipping labels in logistics centres
• Production documentation in manufacturing environments
• Warehouse dispatch documentation
• Industrial tags printed on tractor-fed media
• Batch printing of logistics paperwork and tracking documents
• Top-sheet printing in newspaper and publishing environments
Because the printer is designed for continuous operation, it is particularly well suited to environments where documents must be printed continuously throughout the working day.
What is tractor thermal printing?
Tractor thermal printing uses a tractor feed mechanism to move continuous paper or fanfold labels through the printer. The paper contains small perforated holes along the edges that are engaged by tractor wheels inside the printer.
This ensures extremely accurate paper movement and alignment during printing, which is important when printing large batches of labels or documents.
Tractor-fed printing is commonly used for:
• continuous forms
• fanfold labels
• production documentation
• logistics paperwork
• high-volume batch printing
How is a tractor thermal printer different from a roll-fed label printer?
Most label printers use roll-fed media, where labels are supplied on a roll.
A tractor thermal printer instead uses continuous fanfold media with perforated tractor holes along the edges.
Key differences include:
• Tractor printers support continuous forms and fanfold labels
• Roll printers are typically used for individual labels on rolls
• Tractor systems provide very precise paper alignment
• Tractor printers are better suited to long uninterrupted print runs
What are the advantages of tractor-fed printing?
Tractor-fed printing offers several advantages in industrial environments:
• Precise media alignment during long print runs
• Reliable handling of continuous forms
• Reduced risk of paper skew or misalignment
• Ideal for high-volume batch printing
• Supports larger document formats
These advantages make tractor printers suitable for environments where continuous documentation or labels must be printed without interruption.
How fast can the SOLID 45ET print?
The SOLID 45ET can print at speeds of up to 45 pages per minute, allowing large batches of documents or labels to be produced quickly.
The printer also delivers the first printed page in approximately 2 seconds, which helps minimise waiting time when print jobs begin.
What size media can the SOLID 45ET print?
The printer supports media widths between approximately 110 mm and 240 mm, with a maximum printable width of approximately 213 mm.
This allows the printer to produce labels and documents up to DIN A4 size, making it suitable for larger logistics labels and industrial forms.
Can the SOLID 45ET integrate with ERP systems?
Yes. The SOLID 45ET supports several printer languages and emulations that allow it to integrate with enterprise software systems.
Supported environments include:
• SAP ERP systems
• IBM AS/400 and iSeries environments
• warehouse management systems
• industrial production control platforms
The printer supports languages such as PCL5 and JetCAPS, allowing it to operate within existing enterprise printing environments.
Does the SOLID 45ET support barcode printing?
Yes. The printer supports a wide range of 1D and 2D barcode formats used in logistics, production and warehouse tracking systems.
This allows organisations to print barcode labels directly as part of documentation or tracking workflows.
Can the SOLID 45ET be integrated into automated production lines?
Yes. The printer includes features that allow integration with industrial automation systems.
Optional interfaces allow communication with PLC systems, enabling the printer to operate as part of automated production or packaging processes.
