CUPS: Cannot print to remote printer
I am using RedHat 9 and I have 3 computers depending on the same printer (it's a HP LaserJet 4). I am using CUPS and can print everything perfectly in the computer which is functioning as the printer server (to which the printer is directly attached). So printing to a local printer is ok. What I am having troubles with is printing from the clients. I cannot print from the other 2 computers on which I try to add the printer as a remote printer. Here is what I am doing:
I add the remote printer on the client computers using:
/usr/sbin/lpadmin -p lp -E -v ipp://computername.domain.edu/printers/lp
Then I go to the server and create a file /etc/xinetd.d/printer containing the following:
socket_type = stream
protocol = tcp
wait = no
user = lp
server = /usr/lib/cups/daemon/cups-lpd
I also modify the cups.conf file on /etc/cups (on the server) by uncommenting the following lines
Deny From All
Allow From 127.0.0.1
Allow From nameof2ndcomputer.domain.edu
Allow From nameof3rdcomputer.domain.edu
Ok, this is it for the server. Now, on each of the other 2 computers (clients) I modify the cups.conf file by uncommenting the following lines
But when I type lpq on the 2 clients I get an error message from one of them saying:
Printer 'lp@localhost' - cannot open connection - No such file or directory
Make sure the remote host supports the LPD protocol
I get no error from the second client, but it sends the jobs to print to the lp printer as if it were a local printer, not a remote one. Of course, nothing prints, for there is no local printer on that machine! It was suppose to send it to the remote printer!
Ok, I am confused. I am doing the same thing in both clients yet both of them are trying to do different things.
How can I fix this mess?
I need to get those client computers to print!
Can someone help me?
