PCL Bar Codes and More
Bar Codes and More contains a collection of bitmapped LaserJet PCL soft fonts for printing barcodes. These bar code soft fonts can be used with DOS, Unix, or AS/400 computers and are not recommended for use in Windows. PCL barcode fonts reside on your computer system hard disk and must be sent to your printer before they can be used.<br><br> Once these fonts are sent to the printer, they will stay there until power is turned off. To print a bar code, you send a PCL font selection command to your printer. Then you send your barcode data to the printer. Finally, you send a PCL command to your printer, switching it back to the normal font.<br><br> This set includes five of the most widely used bar code formats, plus OCR-A and OCR-B. These barcodes include bar code types: 2/5, 2/5 interleaved, 3/9, PostNet, and UPC-A. Barcode 2/5 is used to encode numeric data. Bar code 2/5 interleaved lets you encode very high density numeric data. Barcode 3/9 is one of the most commonly used bar codes and offers numeric, upper case ASCII, and some punctuation. PostNet barcode is used to print bar codes for U.S. Mail delivery. Finally, the UPC-A barcode is commonly used on groceries and products throughout the United States and Canada.<br><br> The 2/5, 2/5 interleaved, and 3/9 bar codes come in four different heights and two different pitches. The PostNet font has a fixed height and width. UPC-A comes in two different heights, both with a fixed pitch.<br><br> 3/9 Data Type: Alpha-Numeric+ (upper case only)<br> Bar Code Length: Variable<br> Checksum: Optional<br><br> 2/5 Data Type: Numeric<br> Bar Code Length: Variable<br> Checksum: None<br> 2/5 Interleaved Data Type: Numeric (even number of digits)<br> Bar Code Length: Variable<br> Checksum: Optional<br><br> PostNet Data Type: Numeric<br> Bar Code Length: Fixed<br> Checksum: Required<br><br UPC-A Data Type: Numeric (assigned by Uniform Code Council)<br> Bar Code Length: Fixed<br> Checksum: Required<br>
