A CUPS PostScript Printer Driver's compressor and generator
pyppd is a CUPS PPD generator. It holds an compressed archive of PPDs, which can be listed and retrieved only when needed by CUPS, saving disk space.
To install pyppd, you can use:
# pip install pyppd
Or download the source package, uncompress, and run as root:
# python setup.py install
At first, you have to create a PPD archive. For such, put all PPDs (they might be gzipped) you want to add in the archive inside a single folder (which can have subfolders), then run:
$ pyppd /path/to/your/ppd/folder
It’ll create pyppd-ppdfile in your current folder. This executable only works with the same Python version that you used to generate it. You can test it by running:
$ ./pyppd-ppdfile list
And, for reading a PPD from the archive, simply do:
$ ./pyppd-ppdfile cat pyppd-ppdfile:MY-PPD-FILE.PPD
For CUPS to be able to use your newly-created archive, copy pyppd-ppdfile to /usr/lib/cups/driver/ and you’re done.
The generated pyppd-ppdfile can be arbitrarily renamed, so that more than one packed repository can be installed on one system. This can be useful if you need a better performance, be it in time or memory usage. Note that also the PPD URIs will follow the new name:
$ ./pyppd-ppdfile list pyppd-ppdfile:LasterStar/LaserStar-XX100.ppd $ mv pyppd-ppdfile laserstar $ ./laserstar list laserstar:LaserStar/LaserStar-XX100.ppd

- When testing if the PPD generated from the *Product line already exists in a *1284DeviceID line, we do a case-sensitive test. I think it should be case- insensitive.
