An interface card detachably mounted in a recording device, e.g. a printer, has a first interface (18) connected to a host computer (20), a second interface (19) connected to a control board (11) of the recording device (10), first decompression means (30) for decompressing data received from the host computer (20), memory means (31), and control means (17). The control means is adapted to determine whether the control board (11) is equipped with second decompression means (40) and, if so, to compare control data indicating the performance of said first decompression means (30) with control data indicating the performance of said second decompression means (40). Depending on the comparison result that one of the two decompression means that performs better than the other one is enabled to decompress data received from the host computer, while the other decompression means is disabled. <IMAGE> |
