Great, thanks.

As most (if not all) printer drivers are made for cups (either by upstream 
that links againsts libcupsdriver or by Debian that ships .drv files only), 
and as we have not heard about any efforts from other printer spoolers 
maintainers, I would oppose to have -cups postfixes by default.

My point of view on the matter is that we shouldn't drop packages that might 
be useful to others, such as ijsgutenprint. Let's just do one improvement at 
a time; and for this "action 1", what we need is one printer-driver-* 
package that installs what is necessary for cups to be able to print to the 
printers supported by the given driver.

So, in short, I now consider (and it seems I changed my mind… :-> ) that the 
printer-driver-* namespace is there for "printer drivers that work with 
cups". If there is a way to make those less cups-specific, then people 
should chime in and "show us the code". We should not "allow" non-cups 
packages under the printer-driver-* namespace, at least not currently.
