YaST2 printer wizard fails to detect HP usb printer

English Hardware
1

Hi there

Can someone explain to me why the YaST2 printer wizard does not detect the usb printer, and what can I do to fix it without having to call hp-setup or hp-probe ?

The problem:

In order to make available new printers on an ancient Opensuse 10.3, I had to upgrade a newer version of cups and hplip 3.11.5.
Some of the HP printers require the proper hplip-plugin 3.11.5 which I also installed subsequently.

Our users have no su access rights and indirectly everything must go through YaST2 for reasons of security.

Services detect the HP Laserjet Pro p1102 when the usb cable is plugged in and the unconfigured model is displayed in the YaST2 printer wizard
which fails to connect to the printer during the usb connection step. The updated /etc/cups/printer.conf does not have a correct DeviceURI and
the hplip services remains inactive.

When I copy and paste the uri obtained from the hp-probe command, the YaST2 printer wizard can activate the backend hplip-service in the end and printing works fine (the wizard still did not connect to the printer though). I also get the same printer.conf by running hp-setup. Presumingly it runs hp-probe to detect the printer ? Btw, the ppd is an hpijs.

TIA,
Richard

I had this issue when I did use an USB hub of one specific producer. I changed usb hub, and then everything worked. Do you use an usb-hub to branch the printer?

Nope. Just a direct connection.

You can not expect such an ancient (and not supported) openSUSE and YaST
version to recognize changes in cups and hplip.

You might be more lucky by just using cups, not yast, to install printers.

Cheers. I know it will not be easy, still, I will try to fix it if I can.

Here is a /var/log/message output for the detection of the printer showing that the usblp mount fails. So, I guess, it’s not a YaSt2 printer but a system failure right at the start
somewhere in io/hpmud/model.c and io/hpmud/musb.c.

Conflicting statement in /var/log/message ?

The /usr/share/hplip/data/models/models.dat contains the section

[hp_laserjet_professional_p1102]

with the following (standard) attributes

support-type=2
support-ver=3.10.2

Looking at the function hpmud_get_key_value in models.c (3.12.4) which is called from hp-mkuri, this function could fail (line 625) if the passed arguments don’t match with those above.
The problem is that I don’t know what values are actually passed. hp-mkuri returns a support matrix where the return value 2 indicates the requirement of the plugin.
I guess this number refer to the attribute support-type.

Cant you simply select the ppd file manually?

Either you are running in text mode, or you don’t have QT4. I don’t
remember what QT version 10.3 has.

How important this is, I dunno.

The ppd is ok.

We think that the problem is the recognition of the section name [hp_laserjet_professional_p1102] in model.dat because the section names are not compared correctly (3.11.5)
By shortening the model name and exporting it into the env variable hp_model, the function ‘hpmud_get_key_value’ recognizes the model and the error on line 625 goes away.

In the latest version of hplip 3.13.x this function has been removed.

hp-setup must get around the problem by using hp-mkuri or hp-probe in a different way.

We shall recompile hplip 3.11.5 source code for OpenSuse 10.3 and test our argument.
