Barcode Scanners - Frequently Asked Questions

  1. 1

    The variety of barcode formats available practically ensures you can find a symbology that meets your needs. The most important variables that determine the optimal symbology are the amount of data that needs to be encoded, the space available to print the barcode and the type of data to encode. 

  2. 2
    My customer has rejected the barcoded labels on my shipment but I can read them easily in my facility. Why and what can I do?

    Even though you can read them they might be of poor quality. You may need a true barcode verifier which will evaluate the quality of your printed codes. Most barcode scanners are very tolerant of poorly printed codes. However, only testing conformance to ISO/ANSI standards will guarantee readability by anyone in the supply chain.

  3. 3
    Can I get a true verifier for both 1D and 2D codes?

    Yes. Note that the 2D verification is symbology and size dependent.

  4. 4
    Can we get a permanent record of the verification test results?

    Yes. Outputs to Windows PC’s, MAC’s or portable, thermal printers are available.

  5. 5
    Can I use a verifier portably anywhere in my warehouse or facility?

    Yes. A portable handheld verifier with display will do this.

  6. 6
    Can the 2D scanner read my 1D linear codes also?

    Yes, these imager readers will read most all linear codes as well.

  7. 7
    My Current scanner will not read the barcode which may be a 2D barcode. Do I need a special scanner?

    Laser or linear Imager scanners will not read 2D code with a minor exception.

    2D barcodes require an area imager technology scanner for reading. Some 1D scanners may read 2D stacked codes like PDF 417.  Look at pictures of the codes below to identify your code.


  8. 8
    Do you have the software I can load to enter the scanned information?

    No software utilities are required. The scanner output emulates a keyboard and is independent of the operating system and application.

  9. 9
    Can the scanner plug in to my PDA or phone?

    These portable devices cannot supply enough power to run the scanner. We have rechargeable powered Bluetooth scanners that pair with apple, android and windows operating system devices.

  10. 10
    Will the scanners read the PDF417 code on the driver’s license?

    Yes, and there is a software utility which will parse the multiple fields in the code for all the states.

  11. 11
    I have heard the term 3D barcodes, what are they?

    There are no 3D codes at present. People who refer to 3D usually mean 2D barcodes as they have mixed up the terms.

  12. 12
    What is the advantage 2D barcodes over linear or 1D barcodes?

    2D barcodes offer the ability to encode more characters in a smaller space. In a 1D code, the length grows as more characters are added. There is a practical limit to the length of a linear barcode based on the field of view of the barcode scanner.

    This limitation could be 25 characters depending on the barcode type and print density. By comparison, a 2D data matrix barcode 0.25” x 0.25” can hold 50 characters or more.

Barcode Printers - Frequently Asked Questions

  1. 1

    To print barcode labels, a label format must be created with software that supports bar coding. To print barcodes on documents or reports, the application software needs to support bar coding or additional programming will be required. After the label or form is designed, it needs to be output on a printer that is capable of producing barcodes and supports the specific symbology that is used.

    Because data is encoded using differences between light and dark (and narrow and wide) elements—which are measured in mils, or thousands of an inch—a good quality printer is essential for producing crisp lines and accurate, readable barcodes. Finally, the media must support barcode print quality by not bleeding, running, fading, or otherwise defacing the symbol.

  2. 2

    Many common laser and ink jet printers are capable of producing barcodes, but need to be set up to do so. They often do not have native support for barcode symbologies and need to be upgraded with additional fonts or programming to support bar coding.

    They also lack many of the special features that provide excellent barcode print quality. For more information about the benefits that barcode printers provide and to help determine if your operations need them.

  3. 3

    Barcode printers are available with many common interfaces to facilitate simple integration with a variety of host computer systems. Ethernet, USB, parallel, serial, twinax, and coax cables are available. barcode printers also offer Bluetooth connectivity for wireless integration.

    Management tools enable remote monitoring, configuration, and troubleshooting for networked printers.

  4. 4

    Narrow the field significantly by determining the size of labels that need to be printed. Analyze the conditions the label will be exposed to and its required life span to determine the print method (direct thermal or thermal transfer) and required media support. Printers also differ significantly in the interfaces and network connectivity that they offer.

    The symbologies, graphics, and international characters supported are other important differentiators. Durability and printing volume are also important. For most applications, 203 dots-per-inch (dpi) resolution provides sufficient print quality. However, when higher quality printing is required, such as for very small labels or some 2-D symbologies, 300 or 600 dpi printers should be used.

  5. 5

    Yes, but the print speed listed in the printer specifications (which is expressed as inches per second, or ips) does not always give a true indication of how fast the unit will print. Some printers take a long time to process the label format before they start printing.

    First label out refers to the time it takes from when the print command is sent until the first label in a print job comes out of the printer. First label out time depends on the label size and the printer’s processing power, the interface with the computer system, and the software used in the application. These factors may also result in pauses between labels that prevent full-speed, continuous printing.

    Throughput is a truer measure of how quickly a printer can process a complete print job. First label out and throughput can be evaluated when printers are set up for demonstrations or trials. It is important to use the printer in your actual work conditions to determine if it has the speed and throughput to meet your needs.

  6. 6

    There are two thermal printing methods commonly used to print barcodes: direct thermal and thermal transfer. Each method uses a thermal printhead that applies heat to the surface being marked. Thermal transfer printing uses a heated ribbon to produce durable, long-lasting images on a wide variety of materials. No ribbon is used in direct thermal printing, which creates the image directly on the label material.

    Thermal transfer printers can accept a wider variety of materials and are usually used for permanent or long-lasting labeling applications. Direct thermal printers are usually used to produce shipping labels, picking/putaway labels, receipts, and other common print jobs.
