Here's a workaround, various versions of which can allow you to save the PDF:
- Turn off the print queue for the printer by going to Printer Setup Utility.
- Print the file, but don't reactivate the printer -- choose the Add to Queue option.
- Go into the terminal and su to root. (If you haven't enabled root, use sudo -s to start a root shell.)
- Type cd /var/spool/cups, then identify the file you just printed. Do this by matching the queued file's time stamp to the time you printed the file (ls -l; the file of interest should be at the bottom).
- Copy (don't move) that file out of the spool folder: cp filename ~/Desktop. I don't know what a move (mv) will do to the print system.
- Type cd ~/Desktop to move to your user's Desktop folder.
- Type chown myaccount:myaccount filename to make sure the Finder in your user space will play nicely with the file.
- Peek inside the file and determine whether it's a postscript or PDF file -- you can drop it on TextEdit to see its contents. If it's a postscript file, rename the file to filename.ps. If it's a PDF file, rename it to filename.pdf.
- Confirm the above by dropping the file on Preview. If the file is a postscript file, you can then save it as a PDF file from Preview.
