Well it comes getting a PDF from Windows without Adobe...
it is as simple as having a Linux samba server hanging around.
First, install a generic PS printer nearly any PS printer should work, low or high functionality. Make sure it prints to a file.
Second, make sure you have a mapped drive to a samba server that has GhostScript on it.
Third, print ANY document from ALMOST any application in wondows to the new printer and to the a file on the mapped drive (typically my "Home" Directory I use)
Fourth, SSH to your linux box, locate your file, run ps2pdf included with the ghostscript packages installed on your Linux machine. i.e.:
ps2pdf foo.ps foo.pdf
Give you a straight PDF. Not locked down or anything... so you can modify it if you want to. Or use some of the features in GhostScript to make it read only.
