Ubuntu printer unable to share to XP

kern68 · 01-25-2011, 06:25 PM

There is a printer connected to my Ubuntu box that I would like to share with XP users on my home network. When I browse for a network printer in XP the Ubuntu box is displayed, but does not display the connected printer.

I added the following lines to cupsd.conf:
Port 631
Listen /var/run/cups/cups.sock

and then restarted cups with:
sudo /etc/init.d/cups restart

I have also set ufw to allow incoming traffic through port 631 from each XP machine.

What have I overlooked?

Thank you for any suggestions. GeoK

To share a linux printer to a windoze host, you will have to install and configure Samba server. You define the shared printer in /etc/samba/smb.conf . Once that is done, you have to add a remote printer in windoze. Of course you need the windoze driver for the linux printer in XP. I have never heard of a way to share a linux printer to a windoze client with just cups.

You can use cups only on linux systems to share printers among linux hosts.

Samba is not trivial to configure. Look in the Tutorials, networking section, for how to go about setting up a samba server.

I assume that the printer is located on the Linux Box......
and you want to access from windows...is this correct?

By running cups on you Linux box this can be done without the complication of Samba./
Make sure the printer is online and enter
http://localhost:631
just follow the menus to add a printer....

Using http://localhost:631 I could not get it to work. In xp, the server appears in the windows printer selection box, but no printers appear after making the selection.

Another interesting tidbit is that another Ubuntu box on my home network recognizes the printer and accepts it as a valid printer, but when attempting to print an authentication pop-up appears saying that "Authentication is required for printing document". It asked for a password with "none" to the left of the entry box. The log entry "192.168.0.3 - - [29/Jan/2011:13:13:23 -0500] "POST /printers/HEWLETT-PACKARD-DESKJET-990C HTTP/1.1" 200 515439 Print-Job client-error-not-authorized" is then posted to the CUPS access_log.

If CUPS is requesting authentication, would that prevent windows from displaying the printer? Also, where and how is authentication for CUPS set? I have seen the DefaultAuthType Basic entry in cups.conf and Basic seems to be the correct entry. But the question still remains, where is the authentication set?

Thank you for any help.

It is possible for windows to use CUPS IPP protocol. At first glance I suspect cups is not configured to allow other computers access.

Thank you for the links. One of the links did provide me with a method (nmap) to verify that my port 631 was open, but I am still experiencing the same symptoms as described earlier.

Here is my cups.conf:

Is there anything thats jumps out that would cause any issues?
