Thanks. I wondered whether I should respond to your mail address. Now I did CC 982...@bugs.debian.org if that's what you suggested. > > "bInterfaceProtocol 4" indicates that the printer understands > IPP=over-USB.

Meaning: time table service running No preconfigured system targets lpstat: No printing targets added. BTW: I had IPP-USB configured once, but for that to happen I had to connect the printer using a LAN cable. And I could not print either. But there may have been other misconfigurations be involved, too, as I didn't really understand how to configure a LAN connection for the printer. *As a layman* I am guessing whether this USB mess happens due to timing issues (live ISO is runing in RAM, so runs very responsive). Shouldn't any solution involve solving the apparent conflict between libusb and usblp? Anyway, thanks so far. Michael > > Regards, > > Brian. > > > > > > > > > > Regards, > > > > > > Brian.
