Red Hat :: Not Possible To Set Default Paper Sizes?

The "[SOLVED]" attribute to the How to set defaulter size in RHEL5 thread notwithstanding, the problem really is not solved. I've set my default language to both "C" and to "EN-us" and the problem is that absolutely every single time I print, I have to meander through varying layout print menus to find the "A4" setting and change it to "letter". That, or sacrifice the last two lines on every page because the default size is larger than the actual size. Bad default. It is not unique to Red Hat/CentOS, of course. Same problem exists on Debian and SuSE, too. Why is this such an intractable issue? Why is there not some simple and obvious way to say, "squish all instances of A4 (or "letter") and replace with "letter" (or "A4")!"?
