Thanks for this software! Printing with foo2zjs on my HP 1102w under Linux works like a charm. I had been using hplip, which after a couple of library updates stopped working and instead produced permanent backend crashes. After removing it and installing foo2zjs I could immediately print again. This made my day!
Just one suggestion: It would be convenient if the tarball name was decorated with some kind of version number. This would make it easier to keep track of the different versions.
