No, just make sure to compile it with options


in /etc/make.conf if you need ISO A4 support. It is basically
dialog-driven (/usr/local/share/apsfilter/SETUP) and self-explaining.
Just select printer name, connection, paper, and quality. If you
want to add specific GS options (it uses Ghostscript to convert
PS into printer languages, such as PCL), you can do this via an
easy configuration file, e. g. that's the way I got my duplexer
working correctly.

That's right; in /etc/printcap, there are references to apsfilter
only; here's an example:


This is created by the apsfilter SETUP program, so no need to deal
with this manually (but you CAN if you want to); apsfilter keeps its
config in /usr/local/etc/apsfilter. To extent the example started,
I have /usr/local/etc/apsfilter/Laserjet/apsfilterrc:

		-dNOPAUSE -sDEVICE=ijs -sIjsServer=hpijs 
		-sDeviceModel="HP LaserJet" -dDuplex=true 
		-dIjsUseOutputFD -sPAPERSIZE=a4 -r600'

It's basically a repeatition from /etc/printcap so the filters used
by apsfilter itself can be properly configured. A central file is
also present as /usr/local/etc/apsfilter/apsfilterrc where you can
configure recoders, filters, pretty printing and other stuff, e. g.
you can just

	% lpr foo.png

to print a picture, or

	% grep "void" bar.c | lpr

to get some "stylish" pretty printed output. (By the way, I did switch
that off as it de-arranges source code.)

It's a quite old program complex, but yes - it never failed on getting
my old printers working that CUPS didn't even support. Just try to
add a parallel printer with CUPS that is currently *not* connected
and therefore *not* online. :-)

If PS is fast enough - use it, and get rid of the overhead bloat.
In my case, I intendedly wanted to use PCL as PS works, but is too
slow in comparison to PCL.
