# Samsung CLP-315W on NetBSD

Samsung
[CLP-315W](http://www.amazon.com/Samsung-CLP-315W-Color-Laser-Printer/dp/B001BXS45I)
is a low-end color laser printer, featuring USB, Ethernet, and wireless
access.  It works on NetBSD.  The configuration was relatively painless with
the standard tools supported by NetBSD. There was no need for something as
complex as [CUPS](http://www.cups.org/).

For initial configuration, I used a NetBSD host and standard [[!template
id=man name="dhcpd" section="8"]].  The printer provides its own HTTP server
from which all standard configuration options are available.  Also IEEE
802.11 worked with a NetBSD router.  But unfortunately, a local host is
still required as the printer only speaks a non-standard format language.

The so-called
[foomatic](http://www.linuxfoundation.org/collaborate/workgroups/openprinting/databasefoomatic)
is a prerequisite. This is available from [[!template id=man name="pkgsrc"
section="7"]]:

	# cd /usr/pkgsrc/print/foomatic-filters
	# make install package clean

Samsung uses a special QPDL wire protocol, supported by
[foo2qpdl](http://foo2qpdl.rkkda.com/). For installation, fetch the
sources and compile:

	$ cd /tmp
	$ ftp http://foo2zjs.rkkda.com/foo2zjs.tar.gz
	$ tar xvfz foo2zjs.tar.gz
	$ cd foo2zjs
	$ gmake

If you have problems with the compilation, check the `Makefile` for odd
`CFLAGS` possibly not yet supported by the NetBSD's [[!template id=man
name="cc" section="1"]].  After having the sources successfully compiled,
the required files were organized to `/usr/local`. From the compiled
sources only the following are required:

	# mkdir -p /usr/local/bin

	# cp foo2qpdl /usr/local/bin
	# cp foo2qpdl-wrapper /usr/local/bin

	# cp foo2zjs /usr/local/bin
	# cp foo2zjs-pstops /usr/local/bin

Note the permissions:

	# chown root:wheel /usr/local/bin/foo*
	# chmod 0555 /usr/local/bin/foo*

I used the following as the [PostScript printer
description](http://en.wikipedia.org/wiki/PostScript_Printer_Description)
(PPD) file. In order to avoid wasting the color toner cartridges, two
separate files for monochrome and color setup were used:

	# mkdir -p /usr/local/share

	# cd /tmp/foo2zjs/PPD
	# cp Samsung-CLP-310.ppd /usr/local/share/samsung-mono.ppd
	# cp Samsung-CLP-310.ppd /usr/local/share/samsung-color.ppd

	# chown root:wheel /usr/local/share/*
	# chmod 0444 /usr/local/share/samsung*

By default, the used PPD file does not use colors. This was solved by
editing the `samsung-color.ppd` file:

	# diff -ur Samsung-CLP-310.ppd /usr/local/share/samsung-color.ppd

The following network setup was used: one host named `print.lan` was
dedicated to forward the printing requests to the printer or `printer.lan`. 
This way all hosts inside the LAN can easily use the printer. Two entries
were required for the [[!template id=man name="printcap" section="5"]] file:

	# Color (default; just 'lpr').
	#
	lp|rp:\
		:lp=:\
		:rp=lp:\
		:rm=printer.lan:\
		:lf=/var/log/lpd-errs:\
		:sd=/var/spool/output/lpd:\
		:af=/usr/local/share/samsung-color.ppd:\
		:if=/usr/pkg/bin/foomatic-rip:\
		:mx#0:

	# Monochrome ('lpr -P lpm').  
	#
	lpm|rpm:\
		:lp=:\
		:rp=lp:\
		:rm=printer.lan:\
		:lf=/var/log/lpd-errs:\
		:sd=/var/spool/output/lpd:\
		:af=/usr/local/share/samsung-mono.ppd:\ 
		:if=/usr/pkg/bin/foomatic-rip:\
		:mx#0:

Thus, for color and monochrome output, respectively, one needs only:

	lpr /etc/passwd
	lpr -P lpm /etc/passwd

Remote clients can access the `print.lan` host by using:

	# We have a CNAME record for the printer host inside LAN.
	#
	lp|rp|remote printer:\
	        :lp=:\
	        :rp=lp:\
	        :rm=print.lan:\
	        :sd=/var/spool/output/lpd:\
	        :lf=/var/log/lpd-errs:

Finally, enable [[!template id=man name="lpd" section="8"]] in
[[!template id=man name="rc.conf" section="5"]]:

	lpd=YES
	lpd_flags="-r -n 2"

The output quality is relatively good. There are no visible differences
compared to the output with Windows and Samsung's own drivers.
