The document data. What would actually print.
OK, so on a Mac you can open up the printer window (double-click on printer in Print & Scan pref pane in System Preferences) and then double-click on the job in the window to view it.
For other platforms you can use the cupsfilter program in recent (CUPS 1.4 or newer) to obtain a version of a job suitable for viewing, e.g.:
cupsfilter -j job-id -m application/pdf >tempfile.pdf
