An Introduction to Barcode Equipment
Overview
A comprehensive barcode system includes several key components: specialized software, scanners, printers or labelers, and labels designed for either thermal transfer or direct thermal printing. Additionally, mobile terminals equipped with integrated scanners, displays, and keyboards are essential for mobile data acquisition. For point-of-sale (POS) solutions, laser barcode scanners with high-speed and automatic triggering capabilities are crucial for efficient, hands-free scanning.
Barcode Software
Barcodes are generated using specific software. While options are available for Microsoft Windows, Apple Macintosh computers are often preferred due to their strong presence in the desktop publishing and graphics sectors. Typical barcode software supports common symbologies, automatically calculates checksums, and offers various output options for popular image formats (such as PNG, TIFF, or JPG) and formats like PostScript or EPS.
Although barcode fonts offer a budget-friendly alternative to dedicated generators, they usually fall short in meeting standard quality requirements. Depending on the application, using dedicated barcode-enabled label printing software might be advisable, especially for tasks like printing sequential barcodes for serial numbers or adding logos next to the barcode.
Barcode Scanners
Barcode scanners, or readers, come in various types. The most widely used are laser scanners, which use a moving laser beam for speedy and accurate reading. A more affordable option is CCD scanners, which utilize a row of LEDs and photo detectors. Early models, known as barcode wands or magic wands, used a single LED and photo detector to read barcodes by swiping across them. Unlike laser and CCD scanners that capture the entire barcode at once, barcode wands require manual swiping to read the code.
Barcode Printers
Barcode printers are designed to print barcodes on self-adhesive labels. Most modern label printers operate using either direct thermal or thermal transfer methods. Direct thermal printing applies heat to areas of the label, causing them to darken, similar to older fax machines. While cost-effective, direct thermal labels are light-sensitive and unsuitable for long-term use, making them ideal for temporary applications like short-term address labels.
Conversely, thermal transfer printers use a heat-sensitive ribbon between the print head and label. When heat is applied, ink transfers from the ribbon to the label, resulting in durable prints. However, this method involves additional costs due to the need for both labels and ribbons.
