A CUPS PostScript Printer Driver's compressor and generator
Project description
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.
Instalation
To install pyppd, you can use:
# pip install pyppd
Or download the source package, uncompress, and run as root:
# python setup.py install
It depends on Python 2.x (http://www.python.org) and XZ Utils (http://tukaani.org/xz/).
Usage
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. 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

Issues
Add unit tests.
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.
Generate manpage.
