You're correct, PS doesn't need gs. Because most (all?) applications
output PS when printing (that's a standard), the data can be sent
directly to the printer that processes it.

In case of PCL, apsfilter is quite okay, but you can "just" employ
gs to do the work, so apsfilter is not neededly required. It can
add some functionality.
