This is not a theoretical concern; it happened to me last year. The PDFs I bought today caused even more trouble. The method depends on a clever hack I learned from this Linux Forums discussion.

I downloaded and expanded the source code into a ghostscript With this, I had a fully-functioning Ghostscript system in my home directory that was ready for the Linux Forums hack. Ghostcript a file is sent to a printer, the printer driver first creates a spool file in the native language of the printer, then sends it along to the printer.


After the file is printed, the spool file is deleted. Getting that spool file is the key to creating an unencumbered PDF.

It just so happens that my default printer is a PostScript printer, so the spool file is PostScript, a close cousin of PDF and the format Ghostscript was written to handle.

Instead, it throws up this piece of shit.

That directory is for root access only. But I can get at it from the Terminal:. After I give my administrative password, the second command lists all the files in the cups subdirectory in reverse chronological order.

The PostScript spool file will be the big file near the top of the list, and will have a name like d I delete the print job from the queue and unPause the printer. I am, admittedly, in a very good position because my default printer is PostScript. That would force Reader to create the PostScript spool file I need for the last step.


I now have a new file called d Apart from one or two changes in the directories, this approach should work as well for a Linux computer as it does for a Mac. But I can get at it gbostscript the Terminal: Creating a normal PDF requires just one more step with the modified Ghostscript system.
