Hi, the Google Summer of Code 2010 is over and the only student working for OpenPrinting, Vitor Baptista from Brazil, was successful with the project of effectively compressing PPDs for PostScript printers which are physically residing on the system. I have made use of this software now in the foomatic-db and hplip packages leading to the following savings:
Binary Package *.deb file installed system ------------------------------------------------------------ openprinting-ppds ~4 MB ~5 MB openprinting-ppds-extra ~18 MB ~28 MB hplip-data ~4 MB ~26 MB So on the running system of the Desktop CD 31 MB get saved which can be used for other useful things. All these savings are solely reached by lossless data compression. No functionality is removed from the PPDs, not even comments. Especially the multi-language support of HP's PPDs is conserved. Note also that the splitting of openprinting-ppds and openprinting-ppds-extra was done to remove a big part of the space-consuming PPD files from the Desktop CD. Now as the data is vastly compressed I am thinking about merging the PPDs of openprinting-ppds-extra back into openprinting-ppds and doing away with openprinting-ppds-extra. WDYT?
