Hi Tomasz,

thank you for testing!

Unfortunately, IMO hpcups still loads the plugin... I checked the code
and hpcups doesn't look into models.dat - it loads the plugin either
way, entry in models.dat seems to be checked only during print queue
installation :( .

I have the same experience with scanning on my HP laserjet m1536... it
actually just loads older plugin anyway...

So it wouldn't work on machines were no previous plugin installed.

I'll revert the upstream change and report it.
