why can't use print after installed CUPS ?

[俞强]

i had installed CUPS-1.4.3 from source(configure, make, make install)

now i can configure print via localhost:631, and the test page is perfect.

but the problem is, why can't i see the print in programs ? (etc. in
firefox, file->print, there is no print in print dialog)

thanks all
