Following problem with iprint version part of NW6.5 SP4a:

When installing HP printer driver for e.g. Laserjet 2200 PCL6 + Laserjet
2300 PCL6 via iprint, the "Extras" Tab of the printer driver for using
Watermarks is missing. Installing a new printer with the same
printerdriver directly on the client shows the missing tab for the new
printer (not for the one already installed via iprint).

Any ideas what's wrong here?
