Linux下的无线网卡通用驱动程序

/*

GENERAL
This program converts pbm (B/W) images and 1-bit-per-pixel cmyk images
(both produced by ghostscript) to Zenographics ZJ-stream format. There
is some information about the ZJS format at http://ddk.zeno.com.

With this utility, you can print to some HP printers, such as these:
     - HP LaserJet M1005 MFP		B/W

AUTHORS
This program began life as Robert Szalai's 'pbmtozjs' program.  It
also uses Markus Kuhn's jbig-kit compression library (included, but
also available at http://www.cl.cam.ac.uk/~mgk25/jbigkit/).

The program was overhauled by Rick Richardson to limit data chunk size
to 65536 bytes, add command line options, add color support,
and other miscellaneous features.
