images onto labels using thermal technology. These thermal barcode printers
feature a printhead that is made of multiple tiny heating elements. In many
cases, there are thousands upon thousands of these elements on a single
printhead. A glass coating protects these heating elements. When the glass is
heated, the printhead transfers the image either through a thermal ribbon or
directly upon an appropriately treated label.
Obviously, a key to the successful operation of thermal barcode printers is a
properly functioning printhead. Although even the finest
are not made to last indefinitely (replacement of the part is
assumed), there are some factors that can ruin a printhead quickly or reduce its
life expectancy considerably. Review a few of these common causes of printhead
failure in thermal barcode printers:
Abrasion is often a culprit. The glass shield on the heating elements can be
worn down rapidly when the print head is regularly rubbing against an abrasive
material. The abrasion could come from any number of sources--grit in the area
or labelling featuring a great deal of ?scrap? or ?lint? may be responsible for
sidelining barcode printers by destroying printheads.
Misuse is another common cause of problems. Inappropriate contact with the
printhead by employees is a frequently noted source of printhead ruin. All users
of barcode printers should be instructed in proper use of the equipment and
should not make abusive or potentially damaging contact with a thermal printhead.
Overuse can also degrade a printhead. Most thermal barcode printers are rated to
perform optimally within a certain range. Users who try to stretch their printer
past its natural capacity may inadvertently damage or corrupt a printhead
prematurely.
By decreasing the likelihood of printhead failure, thermal barcode printers can
be a more reliable and affordable part of your business.
Direct Thermal Barcode Printer
Are you the owner of a business that is in need of implementing a barcode system or upgrading some existing barcode equipment? Then obviously you must have done some research and discovered that a barcode system is the easiest way for stores, factories, offices and hospitals to keep up with products, inventory, equipment and files. In case you haven't noticed, we are living in a barcode world. Everything has a barcode. The products we buy, the books we check out at the library, why even the bracelets that moms and their newborn babies wear while in the hospital, all have barcodes.
Technological advances in barcode printer and barcode label software have greatly improved over the past few years. Ink jet and laser printers are not set up to print barcodes without an add-on device. The best way for you to print bar codes is to use a printer specifically designed and dedicated to do only barcodes. Why take a chance with a retrofit? You will ultimately save money and time if you buy a printer that just prints barcodes. You'll negate unforseen hassles and have peace of mind in the long run.
When you check out what's available, you will find that there are two different types of barcode printers. There's a thermal direct printer and a thermal transfer printer. Thermal direct does not require a ribbon, but prints the barcode directly to a label. A printed image is created by selectively heating the coated thermal paper. The heated areas turn black. Some printers have the capability of printing more than one colour by applying heat at different temperatures.
A thermal direct barcode printer is a great option if you are in a competitive industry where quick decisions are made and new product lines can be developed and up and running in virtually no time. Thermal direct labels can be printed fast and can greatly reduce production time on an assembly line, due to the fact that the labels are applied to the produced item, rather than printed directly onto it. This method also allows for changes to the printed information to be made almost instantly. The drawback is that unlike the thermal transfer system, thermal direct cannot be printed directly on different types of materials, because a label has to created first. Also, a thermal direct image doesn't last as well as a thermal transfer image.
Thermal transfer uses a high carbon ribbon that, when heated, transfers the code directly onto the product you are producing. This way, the image that you require can be printed on just about any type of product that you can think of. A coating of ribbon is melted directly onto the material on which the printed image is to be applied. This method would not be good for a production or assembly environment. If used in production lines, the ribbon would need changing often and that could hinder production time. This method would be good for inventory tracking, office filing or hospital admittance tracking.
What ever printer you choose, you need to ensure it will print great quality barcode. Finding a unit that fits your budget is also important, but even more, is quality. A barcode scanner will only read quality bar codes, so you do not want to waste your time and money by purchasing a less than adequate printer. Do your homework, search the internet, and match the unit to your business. There are heavy duty printers, medium to heavy printers, and light to medium printers. Select one that is durable, fast, and has upgrade capabilities, such as additional memory cards, and ethernet connectivity. With the correct barcode printer you can increase the efficiency and profitability of your business.
