That way, the Patch Code can be detected early during the paper transport. Patch Codes are often printed along all four edges of a page. That covers the requirements for many scanners, and it allows the pages to work even if the page is upside down (rotated 180 degrees). Sometimes, the Patch Code is the only information on a page. That is, the ...
Barcode library or Barcode SDK is a software library that can be used to add barcode features to desktop, web, mobile or embedded applications. Barcode library presents sets of subroutines or objects which allow to create barcode images and put them on surfaces or recognize machine-encoded text / data from scanned or captured by camera images with embedded barcodes.
A barcode reader or barcode scanner is an optical scanner that can read printed barcodes and send the data they contain to computer. [1] Like a flatbed scanner , it consists of a light source, a lens, and a light sensor for translating optical impulses into electrical signals.
The earliest, and still [when?] the cheapest, barcode scanners are built from a fixed light and a single photosensor that is manually moved across the barcode. Barcode scanners can be classified into three categories based on their connection to the computer. The older type is the RS-232 barcode scanner. This type requires special programming ...

[4] [5] The ScanJet was released in March 1987, [6] as a compliment to their LaserJet series, which was the first commercially successful line of laser printers ever released, [7] introduced in 1984 and also developed at Boise.
The terminology, however, is different: What others call a character set, HP calls a symbol set, and what IBM or Microsoft call a code page, HP calls a symbol set code. HP developed a series of symbol sets, [8] [9] each with an associated symbol set code, to encode both its own character sets and other vendors’ character sets.
