Abstract
Apparatus and method for compressing Huffman encoded data. The compression apparatus includes a string detector and a record generator. The compression apparatus operates to receive the Huffman encoded data and the length of the codewords used to generate the Huffman encoded data. The string detector then operates to detect each set of repeating strings and each non-repeating string in the encoded data. Each set of repeating strings is replaced with a record that indicates the length of the repeating string, the number of repeats and an instantiation of the repeating string. In addition, each non-repeating string is replaced with a record that indicates the length of the non-repeating string and the non-repeating string. The resulting compressed Huffman data can then be transmitted to a printer.
