As far as you client apps really use the lpr or lp executables you could 
wrap those with a Shell-, Perl-, or Python-script that sets your user 
specific options. But GTK to my knowledge uses the CUPS API directly, and 
LibreOffice does so by default (you may force the environment variable 
SAL_DISABLE_CUPS to true and configure printing using the spadmin utility 
which works on Linux to my experience).

But for the general case, I'd suggest e.g. to set up a prefilter for 
application/postscript that does the following:
(1) if no "*cupsJobTicket: ..." lines are found after the first line 
beginning with "%!", insert the user specific options here and requeue the 
job.
(2) otherwise, do nothing but copying the input to stdout.
