ABSTRACT:
In response to a print job, a character code stream is generated including printable character codes. Each of the character codes is of a first bit length. Command codes to be embedded into the character code stream are padded with an identifier. The command codes and the identifier are of a second bit length that is one-half of the size of the first bit length. The padded command codes are inserted into the character code stream thereby to form a print data stream. The print data stream is transmitted to a printer. The identifier allows the printer to detect and extract embedded command codes while maintaining synchronization thereby to enable character code extraction.
