Description Johannes Meixner 2005-09-08 15:12:30 UTC

Right now I installed 10.0 RC1 on my i386 workstation nelson.suse.de.

At the end of the installation my HP LaserJet 1220 printer+scanner
was set up be YaST printer config by using the CUPS hp backend
(DeviceURI hp:/usb/HP_LaserJet_1220?device=/dev/usb/lp0)
and the required service hplip was started and "insserved".

1.
There should be a user confirmation request before an additional
service is started because admins in business environment like
to be informed which services run on their servers.

2.
The cupsd was stopped after YaST printer config had finished.
This leads to a problem when at the very end of the installation
the YaST scanner config is started (via YaST control center).
If the user selects the SANE hpoj backend for a HP all-in-one device
then the hplip service must be stopped and disabled and the ptal
service must be used instead.
There is a test in the scanner module whether or not the CUPS hp
backend is used (using /usr/bin/lpstat -v | /bin/grep -q ': hp:/'
see /usr/share/YaST2/modules/Scanner.ycp).
When no cupsd runs this test fails in any case and then it is
assumed everything is o.k. and then hplip would be silently
deactivated.
Michal,
Why is cupsd stopped in this particular case?
Wouldn't it be better to simply let it run?

move to later

Comment 2 Michal Zugec 2006-08-31 11:33:29 UTC

reopened

Comment 3 Michal Zugec 2006-08-31 11:33:48 UTC

1 - I think just information will be enought at the end.
hplip service will be run only when hp:// backend is using.
There can be warrning or information when hp backend is selecting (#175323)
Already fixed

2 - please be more verbose or open another bug for this.
I couldn't provide installation today, cups is stopped when hp:// is using or everytime?

Comment 4 Johannes Meixner 2006-08-31 11:49:37 UTC

1 - What I mean is that the user has the possibility to decide
that the hplip services are not started.
Therefore it is o.k. when there is a information when the user selected
the hp backend (bug #175323) so that the user can go back and select
another backend if he doesn't want the hplip services.

2 - I talked about what happened during installation.
If I remember correctly the following happened:
Near the end of the installation after the hardware setup,
the cupsd was stopped. I don't know why it was stopped or what
it stopped (perhaps YaST2-printer?).
If I remeber correctly the cupsd was re-started at the very end
of the installation when the runlevel 5 (or 3) is reached.
The problem which I described happens only when the 
the YaST scanner config is started (via YaST control center)
after the cupsd was stopped but before it was re-started again.
For me it makes no sense to stop and re-start it.
Therefore I suggest to simply keep it running (except the user
has explicitely selected in YaST2-printer during hardware setup
that it should be stopped - e.g. for a "client-only" setup).

Comment 5 Michal Zugec 2006-09-01 11:36:20 UTC

1 - fixed
2 - I will check this, but make separate report, please
