BAR CODES

Thirteen different styles of bar codes and POSTNET are available. Each style (except POSTNET) can be rotated 90, 180, or 270 degrees and printed with or without a human-readable line (HRL). The bar code symbol size and density are also adjustable.

NOTE

Control sequences given in the following text show the proper syntax needed from the host. The second line has examples of code written in the BASIC program language.

Entering and Exiting Bar Codes

Before the printer can print input data as bar code symbols, the bar code mode must be both selected and activated. There are two ways for this to be accomplished depending on the setting of printer option 1 for both 4800 and 4410 ANSI emulation.

SETUP FORMAT MODIFY FORMAT GENPRTOPTS ANSI Printer Option 1 (See Appendix G, Tables 5 and 6) is used to enable the SI (shift in) and SO (shift out) ASCII codes to activate and deactivate special mode functions. In this case, the special mode function is bar codes. With Option 1 enabled, code SO will turn on or activate the bar code mode. SI will turn bar codes off.

ANSI 4800/4410 Strap 1 OUT

Enter the bar code mode of printing with the following control sequence sent by the host. (See Appendix D for strapping options.)

ESC [ 3 t

LPRINT CHR$(27)*."[3t";

Data sent after the above sequence is interpreted and printed as bar codes.

Exit the bar code mode using:

ESC [ 0 t

LPRINT CHR$(27);"[0t";

ANSI 4800/4410 Strap 1 IN

(See Appendix D for strapping options.)

ESC [ 3 t

LPRINT CHR$(27);"[3t";

Selects the bar code special mode.

SO

LPRINT CHR$(14);

Activates bar codes and prints all received data as bar codes. (Only after it has been selected by ESC [3 t above.)
