Industrial label printers make communication possible. They identify products, mark cables and help you track assets – and that’s just the beginning. From work-in-process barcode labels to colorful brand labels, they get work done.
But, which printer performs best? Direct thermal? Thermal transfer? Inkjet? Laser?
This article answers that question, using simple terms, visuals and comparisons. It covers technology and print applications, plus breaks down the advantages of each printer type. Before you add or upgrade a label printer, get to know what’s best for your work.
Label printers that use heat generated by a printhead to print are known as thermal printers. These printers handle a variety of industrial tasks and come in two types: thermal transfer and direct thermal.
Thermal Transfer Label Printers
These label printers use a wax- or resin-coated ribbon to transfer ink onto labels when heated. The ribbon is sandwiched between the printhead and the label. When the printhead passes over the ribbon, it heats up the ribbon’s coating, transferring it to the label to create an image.
If you’re looking for unmatched printing quality and durability for long-term applications, thermal transfer printers are an excellent choice. They provide crisp, high-definition text, graphics and barcode printing that survives chemicals, UV light, abrasions, moisture and extreme temperatures.
Use this printing technology for labels that have to last, such as asset-tracking or barcode labels. Thermal transfer printed labels are also ideal for identifying wires and cables, where frequent upgrades and installations are needed to remain safe and compliant.
Direct Thermal Label Printers
These label printers use chemically treated labels that darken when heated. A heated printhead comes in direct contact with labels to produce an image. This printing method is simple and doesn’t require ink or a ribbon.
If you need labels to last 6 months or less, direct thermal printers are best. They are a great choice for one-time applications where sharp, printed images and text are read and scanned indoors.
Temporary labels are useful in a variety of applications. Popular examples include short-term tracking of products, visitor passes, inventory labels and patient wristbands. Basically, direct thermal printing is for ID that only needs to last a short time.
Inkjet Label Printers
Inkjet technology is simple, but precise. These label printers spray tiny drops of ink onto labels without the printhead actually touching the label material. The ink dots are 100 microns wide (a micron is one thousandth of a millimeter) and require precise positioning to achieve their high-quality images.
Use inkjet printing to custom-print signage and unique identification. These printers offer high-quality printing with little maintenance. Plus, they require very little time to set up and adjust.
Due to an inkjet printer’s color capabilities, it’s ideal for safety messages like arc flash and hazardous material labeling. It can also be used to mark facilities: pipe marking, directional signs and Lean/5S processes. And in labs, switching to color printing reduces errors and makes sample identification easier.
Laser Label Printers
These label printers melt toner powder onto labels to produce a print. They use an electrical charge to attract toner from its cartridge to a drum. Then, the toner particles are pressed onto labels while heat from a fuser fixes the image in place.
Laser printers are recommended for high-speed printing. They produce a clean, professional look, especially with text and line graphics. Known for efficiency and low operating costs, they are ideal for creating labels, tags, tickets and reports.
