[cups] (/usr/lib64/cups/backend/smb) stopped with status 1

Fri Feb 2 19:07:13 PST 2018

I have already included the filename on the command-line.
Indeed, my filename is "2.pdf".
However, when I am reading the man of smbspool, it seems that I do not follow the synopsis:
smbspool {job} {user} {title} {copies} {options} [filename]

What I am currently doing is something like that:
smbspool {printer} {job} {user} [filename] {copies}

I am trying to apply manually to the smbspool command the same arguments than the ones CUPS is applying to the smbspool command:
---
$ grep "args" error_log
D [31/Jan/2018:09:35:36 +0100] [Job 5] Gutenprint: command line: Xerox-WorkCentre-5325 \'5\' \'yugiohjcj\' \'2.pdf\' \'1\' <args>
---
But I don't think these are arguments for the smbspool command.
It does not follow the synopsis of that command.
It seems that these are arguments for gutenprint.

Is there a way to see what are the arguments applied by CUPS to the smbspool command please?
That could be useful to understand why /usr/lib64/cups/backend/smb stopped with status 1.

Well, I have to admit that some questions in my messages are related to Samba but some others are clearly related to CUPS.
CUPS is calling the Samba backend so there is a relationship between these two programs.
My question 1) is for Samba I guess but my questions 2) and 3) are for CUPS.
I am able to print with Samba alone but not with CUPS using the Samba backend so that's why I think that the CUPS mailing list is a good place for my problem.
If you feel that none of my questions are related to CUPS, just ignore me please and I am sorry for that.
