Many thanks to jpd@usl.edu (James Dugal) who sent me his modified BSD 4.3
lpd source package.
Using this, I was able to determine (since there is a lack of ANY documentation
on printer filters) that the lpf filter shipped with SunOS is not exactly a
generic pass all printer filter. Perhaps this was causing some problems.
Using the source, I hacked out a generic printer filter that simply passes
stdin to stdout, and counts the characters. It then logs them to the
accounting file. This is a very crude measurement of course, but it will
give me some information in the short term, and allows me to modify the
source in my spare time to actually read the HPGL and calculate the number
of feet of paper.
Here is the code if anyone is interested.
