on my freshly installed NS7 I have a printer (HP laserjet 1300) configured through USB. I can print a test page through the CUPS config page on http://192.168.1.100:631.
My linux mint machine on 192.168.1.42 can automatically find the printer, and send a print job to it, but nothing comes out. There is no job in the cue.
Worked for me
I changed
<Location /
Order deny,allow
Deny From All
Allow From 127.0.0.1
Allow From 192.168.1.0/255.255.255.0
</Location
to
<Location /
Order deny,allow #Deny From All
Allow From 127.0.0.1
Allow From 192.168.1.0/255.255.255.0
</Location
and
<Limit All
Order deny,allow
Deny From All
Allow From 127.0.0.1
Allow From 192.168.1.0/255.255.255.0
</Limit
to
<Limit All
Order deny,allow #Deny From All
Allow From 127.0.0.1
Allow From 192.168.1.0/255.255.255.0
</Limit
Now everything works. However, as I understood the other post, this will come back at me on the next update. I guess this is Solved for now, I will just leave it for the guys in the other post to resolve.
I had problem using OS/X, and I still have to get AirPrint working, but the fast and easy way to solve my own problem was to choose a Samba shared printer rather than direct IP printing.
