[Pkg-samba-maint] Bug#784850: samba: Samba doesn't get printer list from cups

[Wendigo]

Package: samba
Version: 2:4.1.17+dfsg-2
Severity: normal

Dear Maintainer,

In a fresh Debian Jessie setup running with the KDE desktop.

CUPS recognises and prints to remote printers attached to Windows 7 machines. 
CUPS recognises and prints to printer connected directly to the Jessie server

SAMBA can share and read files from Windows 7 machines.

The printer connected to Debian appears as shared in the CUPS web interface and
Windows 7 clients can print directly to CUPS using IPP  and the printer address:

http://harpia:631/printers/Stylus-COLOR-777


But Samba doesn't show the printer connected to Debian Jessie as available.
Using smbtree -U. doesn't show the printer in Debian as available and people coming 
with their laptops can't see the printer in Windows. 


It seems that Samba can't connect to CUPS to get the list of available printers in the
Debian server. 
It can also be a problem in CUPS but since it can share the printer directly to Windows using
IPP it seems to me that the problem is with samba.


The setup and the same smb.conf worked perfectly in Debian Squeeze, the same problem
happened in Wheezy and happens now in Jessie. 


Here is the smb.conf file
testparm shows it as correct.

----------------------------------

[global]
workgroup = KAMEHOUSE
netbios name = HARPIA
security = user
map to guest = Bad User
printcap name = cups
disable spoolss = Yes
show add printer wizard = No
printing = cups
name resolve order = bcast host wins lmhosts
load printers = yes

[data]
comment = data1
path = /media/ntfs/share
read only = Yes
guest ok = Yes

[media]
path = /media/deposito/Media
read only = Yes
guest ok = Yes

[printers]
comment = Printer in Linux
path = /var/spool/samba
guest ok = Yes
printable = Yes
use client driver = Yes
browseable = Yes

--------------------------------------

Note: If I add this to smb.conf

[Stylus-COLOR-777]
comment=Local printer
printer=Stylus-COLOR-777
path=/var/spool/samba/
printing=cups
printcap name=cups
printable=yes
use client driver=yes
guest ok=yes
writable=no


then the printer is shown as available to smbtree -U and Windows 7 clients
but trying to add the printer shows
Windows couldn't connect to the printer
Error 0x0000002e in Windows

It doesn't even let you choose the printer model or driver. So it seems that
samba is showing the printer name but is not communicating with cups or getting the list of printers from CUPS.


Thanks
