allow configuration of offline USB printer

Feature state

openSUSE Distribution
Unconfirmed

Description

Now it's impossible to configure a local printer is it's not detectedn why?

User benefit:

Linux/openSUSE have a lot of printers available. USB or // ones don't need to be connected to be installed if we know all of them.
It's very desirable when you try to move some user from windows to openSUSE and have to configure openSUSE when not all the hardware is present.
This can be done with any network printer but not with local.

I know most local printer are detected and installed nearly automatically, but it's even better if it's done in advance.

Usecase

my friend come at my home with his 11.4 install and ask me to configure his USB printer. I can't do it with yast, cups or hpsetup.

Years ago I could do with vi, but now it's a bit too difficult with cups to do things by hand

By design how CUPS works for USB printers
since CUPS 1.2 (i.e. since openSUSE 10.2)
you cannot set up an USB printer which is not autodetected by CUPS so that you cannot set up an USB printer which is not connected.
Only the new style USB DeviceURI
usb://make/model?serial=number
can be used because only this kind of URI
works for more than one USB printer.
The old style URI can permute which printer is
accessed via which /dev/usb/lp* device node depending on the sequence how the printers
are switched on.

When the CUPS backend "usb" cannot detect the printer it cannot report the right
usb://make/model?serial=number device URI
for the particular model. But without the right device URI it is not possible to set up a printe queue. For background information see http://en.opensuse.org/SDB:CUPS_in_a_Nutshell
