location of user-specific CUPS/postscript/lpr config files?

hi, update: I solved the problem (below) by resetting the contents of $HOME/.cups/.

I really do mean user-specific (versus global) preferences, so I imagine the info/settings probably live somewhere in $HOME/, but my Linux/Fedora/CUPS printer config knowledge has become outdated and quite rusty... I tried some obvious things -- like blasting away the $HOME/.gtklp that exists if one has GtkLP installed (a GTK frontend to CUPS) -- but all this was to no avail, my page-scaling problem persists.  I've also searched extensively online for the info (queries like "linux postscript user customization file"), but still can't find anything.

I learned the following from various troubleshooting efforts and tests:

(I tried snooping around $HOME/.gconf and usual places like that, but not 100% sure what sort of file I'm searching for and I don't see anything obviously awry).
