Hi Mario,
sorry for top posting...
THANKS for sharing your work, Mario!!!
Could you please do this:
git clone git://code.x2go.org/cups-x2go.git cd cups-x2go <put your changes into the files there> git diff -> then send the diff to patches@x2go.org
Same for x2goserver.git.
This will be much easier to read and use.
Thanks, Mike
@Morty: how do you send Git patches via mail. With you they seem to
come directly from the git command. Could you add some lines in the
wiki on that?

When you print from your X2Go desktop to the X2Go printer, what happens? Thanks - JohnWhen I try to print from the client x2go desktop to the x2go
printer nothings happens! The print job is queued in the spool of the x2go printer (cups server), nothings happens from the client side!What I need is to understand how to configure the printing
system, on both the client and the server side, to achieve redirect the print jobs on the
server side to client's local printer. I saw no documentation on this configuration.This is achievable with the current version of
x2goserver/x2goprint/cups-x2go?Since then, thanks for your answer <snip> Is the cups server running on the X2Go server? Yes! x2go server and tne cups server are in the same PC.
If not, I believe it needs the ability to SSH to it to transfer the file.
The printing is also dependent upon sshfs working properly. This should be relatively automagic assuming it is not being blocked by Windows.
On the X2Go server side, if you issue a mount command, do you see a print spool directory, e.g., sshuser@127.0.0.1:/cygdrive/C/DOCUME~1/MYID~1/X2GO~1/S-9270~1/spool on /tmp/spool_myid/myid-63-1312305869_stDKDE_dp32 type fuse.sshfs (rw,nosuid,nodev,max_read=65536,user=myid) I can see this type of mount! being logged in with my username, from the server in a console;
can change dir to /tmp/spool_mario/mario-60-1312310981_stDGNOME_dp32 and I created 2 files in that directory: $ Echo "some text"> x.txt $ Echo "x.txt"> x.txt.readyOn the client PC, the window for print for x2go emerged.
Pressing the print button gave an error:
Window Title: Printing error Failed to execute command: C:Archivos de programaGhostGumgsviewgsprint.exe -query -color C:/Documents and Settings/mario/.x2go/S-mario-60-1312310981_stDGNOME_dp32/spool/x.txt [OK button]
But that is not important; for now!
The important thing is that apparently the print jobs are not
placed / created in the directory /tmp/spool_mario/mario-60-1312310981_stDGNOME_dp32why? <snip> I really don't know. It has been quite a while since I setup X2Go

If I recall correctly, the X2Go print driver is a script or somewhere there is a script involved which places the files in the appropriate tmp directory. Is there any chance that script is not executable?
You may wish to find that script and edit it by adding some debug information. I usually add a logger command to send output or simply statements about where I am in the script to the syslog. This way, you can find out where the script is breaking. Hope that helps - John
Hello people!
I changed the cups-x2go script, so I could print on a client XP. Also modify x2goprint, but not its functionality, just add a few
lines to logging. The problem, from what little I could understand, is that the user
x2goprint it is not created in the installation package x2goserver.*.deb, #·addgroup --system x2goprint # adduser --system --no-create-home --shell /bin/bash --group --home /var/spool/cups/x2goprint x2goprint # passwd -d x2goprint #### Surely there is a better way to create this user. Besides having some leftover variables like $sess. And x2goprint generates a problem when it checks if there is a mount point in the session called $spooldir when there is *additionaly* a shared directory configured for the remote user on the client PC for export.Y commented the 2 script with #mario# tags for clarity
