An apparatus and method to compress data for a print head divides print head nozzle firetime instructions into a plurality of bytes. A control word represents each byte by one bit. Bytes containing data are set from a host computer to a printer. Empty bytes are represented by a "0" in the corresponding bit in the control word. Empty bytes are omitted from transmission. At decompression, omitted bytes are treated as blank space. Bytes are organizing according to print head architecture, nozzle array and printing sequence, for example, in even and odd groups.
