Setting up CUPS and Splix on a NetBSD system (draft) 

for Samsung and new-Xerox printers 

Introduction 

Versions used: 

- NetBSD 6.1.2 (GENERIC) amd64 

- pkgsrc 2013Q4 & wip-20140118 

Installing CUPS and Splix 

Install and start the CUPS daemon, 

pkg_info | egrep -i 'foomatic|ghost|a2ps|poppler|cups|lpr|splix'

#pkg_delete LPRng-core LPRng-doc LPRng

echo $PKG_PATH

pkg_add cups

cd /etc/

cp /usr/pkg/share/examples/rc.d/cupsd rc.d/

cat >> rc.conf <<EOF9

cupsd=yes

EOF9

rc.d/cupsd start

ps aux | grep cups

Make sure you've got pkgsrc 2013Q4 as /usr/pkgsrc/ so it doesn't conflict with the binaries you are using, 

cd /usr/

#rm -rf pkgsrc*

cvs -q -z2 -d anoncvs@anoncvs.fr.netbsd.org:/cvsroot checkout -r pkgsrc-2013Q4 -P pkgsrc

fetch and extract latest wip into that, 

cd pkgsrc/

wget ...

tar xzf pkgsrc-wip-20140118-snapshot.tar.gz

and install the additional Splix PPDs for your Samsung or new-Xerox printer, 

cd wip/splix/

make show-depends

make show-options

unset PKG_PATH

make

make install

Configuring CUPS 

Make sure the daemon is providing its web service, 

netstat -an -f inet | grep 631

Enable remote access to the CUPS web interface, 

cd /etc/

ln -s ../usr/pkg/etc/cups

cd cups/

cp cupsd.conf cupsd.conf.dist

change, 

Listen 0.0.0.0:631

<Location />

  Order allow,deny

Allow 192.168.0 

</Location>

<Location /admin>

  Order allow,deny

Allow 192.168.0 

</Location>

<Location /admin/conf>

  AuthType Default

  Require user @SYSTEM

  Order allow,deny

Allow 192.168.0 

</Location>

and apply, 

cd ../

rc.d/cupsd restart

Configuring a printer 

Try to configure the printer through the web interface but you'll see it's a no go, 

Administration > Add a printer (identify as root)

or add the printer from the command line, 

lpadmin -p scx1 -v usb:/dev/ulpt0 -P /usr/pkg/share/cups/model/samsung/scx4200.ppd 

#lpadmin -p scx2 -v usb:/dev/ulpn0 -P /usr/pkg/share/cups/model/samsung/scx4200.ppd 

With libusb disabled (install binary cups pkg, then compile ghostscript with cups option, then instyou should see the USB devices provided by the kernel. With libusb enabled... (TODO) 

Additional notes 

To wipe out CUPS entirely from your NetBSD system, 

#pkg_delete poppler poppler-utils cups splix ghostscript ghostscript-fonts

pkg_delete cups splix ghostscript foomatic-filters-cups foomatic-filters ghostscript-gpl ghostscript-fonts

rm -rf /var/spool/cups/

rm -rf /var/run/cups/

rm -rf /var/log/cups/

rm -rf /var/cache/cups/

rm -rf /usr/pkg/etc/cups/

rm -f /etc/rc.d/cupsd

userdel -r lp

groupdel lp

and see what's left, 

pkg_info | egrep -i 'foomatic|ghost|a2ps|poppler|cups|lpr|splix'

Ready to go 

Try to print something either using the CUPS intercface (print test page) on the printer page, or on the command line with, 

echo line 1\\nline 2 | /usr/pkg/bin/lp

Troubleshooting 

If you get this error while trying to print something, e.g., 

/usr/pkg/bin/lp: Unsupported document-format "text/plain".
