Q: I am running PDF Studio on 64bit Debian squeeze with Gnome desktop. When I try to print I get the error message: “No print service found”

A: It is a setup problem that many debian squeeze users have encountered.

To resolve this, open /etc/sysctl.d/bindv6only.conf and set net.ipv6.bindv6only=0, then restart the procfs with invoke-rc.d procps restart
