In addition, choice of print media can significantly affect the readability of bar codes. See Using the printer menus and Print media guidelines for information on printer settings and print media considerations to help optimize the readability of printer bar codes and OCR characters. Before purchasing any specific solutions, print a sample of OCR characters or bar codes on your print media. Then, verify readability with the actual devices that will be used to read them. The manufacturer does not warrant that a specific bar code reader will be able to read the bar code images as printed or that a specific OCR reader will be able to read the OCR characters as printed. Symbol sets A symbol set is the collection of alphabetic and numeric characters, punctuation, and special characters available in the font you select. Symbol sets support the requirements for different languages or specific applications, such as math symbols used for scientific text. In PCL 6 emulation, a symbol set also defines which character will print for each key on the keyboard (or more specifically, for each code point). Some applications require different characters at some code points. To support multiple applications and languages, your printer has 83 symbol sets for the resident PCL 6 emulation fonts. Symbol sets for PCL 6 emulation Not all font names support all of the symbol sets listed.
