Bug 449900

+++ This bug was initially created as a clone of Bug #449860 +++

Description of problem:
When adding a new printer (HP LaserJet 2420dn) many drivers that are not
currently installed are listed. It would be preferable if after entering the
make/model the user was warned of this and told that the driver would be
downloaded as part of the device install. The troubleshooter does this but it
would be much better to not run it at all.

Version-Release number of selected component (if applicable):

Name        : system-config-printer        Relocations: (not relocatable)
Version     : 0.7.82.3                          Vendor: Fedora Project
Release     : 2.fc9

How reproducible:
Add new printer, many drivers are not installed by default

Steps to Reproduce:
1. Add new printer, even if the driver doesn't exist sys-config-printer will try
to use it.
2. Print test page, a warning will pop up that there is a problem.
3. Using the troubleshooter will locate the driver.

Actually what's meant to happen is that you should get a dialog asking to
install the package as soon as you add the printer queue.

It's quite expensive to determine whether extra packages are required for a
particular printer/driver combination, so we can't really do this check when
displaying the driver list.  However, it could be done as part of the
add-printer wizard after 'Next' has been clicked.
