Appendix B: Code pages
B-20
Special character set OCR-B1
The listed code pages show the different character sets that are avail-
able in the various printer´s typefaces. For example, Codepage 437
(USA) can be printed in Roman, Swiss, Courier etc.
In contrast to that the selection of OCR-characters (Optical Character
Recognition) defines the character set as well as the typeface. The
OCR-Code contains fixed characters, which can be read and proc-
essed by every OCR-scanner.
In Letter Quality (LQ) you can select OCR-B1 character sets, a deriv-
ative of the OCR-A-typeface and easy to read.

Although the OCR-typeface is available in various pitches, readibil-
ity is only given in 10 cpi .
The actual, error free readibility of typefaces like OCR-A, OCR-B or
Barcodes (EAN, UPC, Zip) is influenced by ...
● the printing process (resolution, sharpness of edge).
● the technical quality of the printer.
● the quality of the print medium (toner, ribbon).
● the quality of the printing material (shine, smoothness, coating,
age, reflection, surface´s consistency).
● the technical quality of the scanner.
