You should, if this queue is shared, be able to see its URI from the client with 'lpinfo -v' and 'lpstat -l -e'. What do they give? > The is the client; > scheduler is running > no system default destination > lpstat: Forbidden > lpstat: Forbidden > lpstat: Forbidden > lpstat: Forbidden > lpstat: Forbidden I've never come across that before. "Forbidden" simply shouldn't happen. It looks like the client is denying access to its cupsd. A common way to access the print queue on the server is to set a queue up on the client. The state of this *local queue* is shown by the lpstat command run on the client. What is happening on the server is of no consequence. Are you using a client.conf in $HOME/.cups or /etc/cups? Anything in /etc/cups/ppd? What do you have for 'ls -l /etc/cups/cupsd.conf? -- Brian.

Correct is in your case: Allow 192.168.1.0/24 Regards, Klaus. -- Klaus Singvogel GnuPG-Key-ID: 1024R/5068792D 1994-06-27

Cups no longer accepting remote connections for printing.
HI, My printer on a remote machine works when access from that machine, I've checked port 631 isn't blocked using Xnat, but I can't work out why I can't print. All the user pages say forbidden, and a test page from my local cups hangs. I'm using Buster on this machine currently. Here's my cupsd.conf, Thanks James # Configuration file for the CUPS scheduler.
