Added logs.

Juanito:
Does the directory /usr/local/etc/cups/ppd exist?

Yes, since I've copied my ppd file into it.

What doesn't exist is the /usr/local/share/cups/model/ (please see error_log) in which it seems to look for the ppd file.

So I've made it manually and copied my file into that. No error returned, but it doesn't work yet.

Hi t18
I found these lines from error_log interesting:

--- Code: ---E [14/Apr/2025:08:22:28 +0000] [CGI] Unable to scan \"@LOCAL\"!
E [14/Apr/2025:08:23:18 +0000] [cups-driverd] Unable to open \"/usr/local/share/cups/model/mnt/sda2/Generic-GDI_Printer-gdi.ppd\" - No such file or directory
E [14/Apr/2025:08:23:18 +0000] [Client 5] Returning HTTP Forbidden for CUPS-Add-Modify-Printer (ipp://localhost:631/printers/Samsung_ML-1210) from localhost

--- End code ---

Line 1 seems to suggest difficulty accessing localhost.
I noticed this note in  libcups.tcz.info:

--- Code: ---Comments:       common unix printing system libraries
                ----------
                howto print from a cups client to cups server
                create a file of the form:
                $ cat /usr/local/etc/cups/client.conf
                ServerName 192.168.1.200
                replace 192.168.1.200 with the ip address of your cups server
                and modify hosts as follows:
                $ cat /etc/hosts
                127.0.0.1 cups_client localhost localhost.local
                192.168.1.200 cups_server cups_server.local
                replace cups_client and cups_server with the hostnames from your client/server
--- End code ---

Lines 2 and 4 contain paths that look a little odd:

--- Code: ---/usr/local/share/cups/model/mnt/sda2/Generic-GDI_Printer-gdi.ppd
                            ^^^^^^^^___ odd part
/usr/local/share/cups/model/home/tc/Generic-GDI_Printer-gdi.ppd
                            ^^^^^^^___ odd part
--- End code ---

Line 3 suggests a permission error, possibly related to
line 1, or maybe the  /printers/  directory itself:

--- Code: ---ipp://localhost:631/printers/Samsung_ML-1210
--- End code ---

Ok, I'm using a local printer connected to the USB port, so I thought it's not necessary to configure the network.

I have now enabled the debug loglevel and issued th following commands:


--- Code: ---sudo /usr/local/etc/init.d/cups start

sudo mkdir /usr/local/share/cups/model/

sudo cp /home/tc/Generic-GDI_Printer-gdi.ppd /usr/local/share/cups/model/

sudo lpinfo -v

sudo lpadmin -p Samsung_ML-1210 -E -v usb://Samsung/ML-1210 -m Generic-GDI_Printer-gdi.ppd

sudo cupsaccept Samsung_ML-1210
sudo cupsenable Samsung_ML-1210

sudo lpstat -p Samsung_ML-1210 -l

sudo lpoptions -d Samsung_ML-1210

sudo lpstat -d


--- End code ---

This is the access_log file:

--- End code ---

Printing a file via:   lp myfile.txt    doesn't work (Filter failed).

Attached is the error_log file.

I haven't found any explanation about the "(cups-brf) stopped with status 13" error.

Any hints?

Many thanks
