What is a Thermal Printer?

Thermal Printer

If you work in a warehouse, factory, or industrial facility that requires printing bar codes or other media, you've probably experienced the pain of printing these with a laser printer. It's a hassle, produces vast amounts of waste, and can be time-consuming. You've probably considered making the switch to a thermal printer. If you haven't yet done so, Thermal printing is a great alternative that allows for less waste, ease of use, and quicker printing. When work environments are labeled effectively, workers are safer and more efficient, so it's important to have to right tool for the job.

Technological advances and the speed and quality of thermal printing has made this method increasingly popular in commercial enterprises of all varieties. Do you go to the movies? Your ticket was printed with a thermal printer. Received a receipt from your order at Chipotle? Made a label for yourself for some honey-roasted cashews from the bulk bins at the grocery store? Taken a number at the DMV? Purchased a lottery ticket? Chances are a thermal printer was used for all of these examples.

In deciding whether or not thermal printing is best for your company, it's important to examine the options available, and what this method of printing can do improve your business processes. The Lean method of Kaizen dictates that companies should always strive for continuous improvement, and integrating thermal printers into your facility might be the right way to improve.

Thermal Printing in a nutshell

To put it simply, thermal printing uses heat to copy an image onto a chosen material. Inkjet printing uses ink to copy an image onto chosen material. In the early days of this printing technology, direct thermal printers resembled branding irons, whereas inkjet printers resembled tattoo guns. For specific detail and complicated coloring, inkjet was the clear and superior option.

Nowadays, advances have given thermal transfer printers the best of both worlds: the high-quality images of inkjet and the speed and convenience of direct thermal printers. Inkjet printing still delivers the highest quality image if you're using paper as your medium, but for other media, thermal transfer printing is the best way to go.

Let's take a closer look at the two main methods for thermal printing: thermal transfer and direct thermal.

Thermal Transfer

Thermal transfer printing occurs by a process that uses heat in order to produce an imagine on paper, a label, or some other such material. The image is created by melting a coating so that it stays glued to the intended material. This technique provides high-quality image printing that can't compare to other on-demand printing options.

Thermal transfer printing uses a ribbon to produce images onto desired materials. This method is ideal for environments that require printing a variety of things, since thermal printing can print effectively on a larger array of media than direct thermal models, including paper, polyester, and polypropylene materials. Thermal transfer printers are able to print pipe marking labels, wall signs, tickets, tags - just about anything. One thing to keep in mind: when you change from one material to the other, you'll want to make sure the targeted material - that is to say the material on which you want something copied - and ribbon are matched. This will ensure stellar performance.

The accurate media-ribbon combination can enable users to create high-quality labels that withstand environmental extremes, sun damage, chemical and water exposure, etc.

Typical uses for thermal printers utilizing thermal transfer method:

  • Pipe marking
  • Inventory identification
  • Instrument identification
  • Instructive labels
  • OSHA-compliant notifications
  • Safety warnings
  • Certification labels

Direct Thermal

Direct thermal printers use chemically treated, heat-sensitive media that darkens when applied to a thermal printhead. Unlike Thermal transfer printers, direct thermal printers have no ribbon, ink, or toner. Because these don't require lots of components, direct thermal printers make for easy usage. Because there are less parts to direct thermal printers, they're more durable and tougher than inkjet printers. Most mobile printers - the kind you might see in a warehouse, for example - utilize direct thermal technology.

The downside to this method is that direct thermal images that our overexposed to heat, light, or other harsh environments will darken, consequently rendering them unreadable. Direct thermal printing isn't intended to last a lifetime, and the readability of direct thermal printing varies on usage conditions.

Best uses for direct thermal printing are for simple images, such as:

  • Shipping labels
  • Receipts
  • Ticket printing
  • Various barcode applications

Determining the Right Thermal Printer for your business

Now that we know which kind of thermal printers do what, it's time to decide which type of printer will be best for our facility's needs.

Direct thermal printers have limited printing capacities, but most thermal transfer printers have the capability of printing either thermal transfer or direct thermal. This versatility is very valuable if a business needs its thermal printer to do both methods of printing, but if they only need direct thermal capabilities, these thermal printers are generally less expensive. If your business requires any kind of labeling - from pipe marking to OSHA compliance - then a thermal transfer printer will be the smart choice.

For those looking for thermal printers that are easy to use, fast, and have industrial-strength toughness, LabelTac® Printersare the best option. This line of printers was designed to serve the needs of industrial facilities. These printers come with LabelSuite™ software, which makes it easy to design labels to fit your company's needs, and to include OSHA-compliant headings and signal words.
