Comment 57 for bug 45099

Referring to the title of this bug (IPP: Only RAW printing works) I have the same problem here with a DeskJet-890C printer. It is connected to my desktop computer and accessing it via IPP with my laptop fails if I choose the normal procedure to install the printer (i.e. Printer --> Network --> IPP:/server/printers/DekJet-890C --> Selection Driver HPLIP 0.9.7) Then the output is always
 -12345X@PJL ENTER LANGUAGE=PCL3GUI
in the first line followed by some lines of variable garbage.
On both systems (server and laptop) Dapper has been installed and both use the same versions of cups related packages.

$ dpkg -l | grep cups
ii cupsys 1.2.2-0ubuntu0.6.06
ii cupsys-bsd 1.2.2-0ubuntu0.6.06
ii cupsys-client 1.2.2-0ubuntu0.6.06
ii cupsys-driver-gutenprint 5.0.0~rc2-0ubuntu6
ii gnome-cups-manager 0.31-1.1ubuntu13
ii libcupsimage2 1.2.2-0ubuntu0.6.06
ii libcupsys2 1.2.2-0ubuntu0.6.06
ii libgnomecups1.0-1 0.2.2-1ubuntu5.1
ii libgnomecupsui1.0-1c2a 0.31-1.1ubuntu13

There are NO errors in /var/cups/error_log.

The printer only works via IPP after I installed a printer in RAW mode as described above.

I might be worth noting that this problem only occurs AFTER updating the laptop from HOARY TO DAPPER last week. Before that time printing went fine the usual way (i.e. no RAW printer needed). The server, which is my dekstop computer actually, has been updated since release of Dapper and was kept up to date since then.
So it's a pretty good guess that it hast something to do with the client. The Dapper installation on the laptop computer were a complete re-install. There are no remnants of Hoary whatsoever.

Kind regards
