Hi, I'm stuck with resolving my printer issue. Maybe someone here can help me out. Long story: https://bbs.archlinux.org/viewtopic.php?id=148474 Short version: I reinstalled cups, removed all leftover files in /etc, /usr which wasn't owned any package. Samsung unified driver got replaced with splix-svn 307. Now cups doesn't see my usb printer. On a laptop with clean cups install it works. What interesting that the printer is recognized, lsusb, dmesg shows it. And usb backend called manually detects it, too: |# /usr/lib/cups/backend/usb DEBUG: list_devices DEBUG: libusb_get_device_list=10 DEBUG2: Printer found with device ID: MFG:Samsung;CMD:PCL5E,SPL,FWV,EXT;MDL:SCX-3200 Series;CLS:PRINTER;MODE:SCN;STATUS:BUSY; Device URI: usb://Samsung/SCX-3200%20Series?serial=Z509BFEB902638M&interface=1 direct usb://Samsung/SCX-3200%20Series?serial=Z509BFEB902638M&interface=1 "Samsung SCX-3200 Series" "Samsung SCX-3200 Series" "MFG:Samsung;CMD:PCL5E,SPL,FWV,EXT;MDL:SCX-3200 Series;CLS:PRINTER;MODE:SCN;STATUS:BUSY;" "" root ~ # lpinfo -vl network http network lpd network socket network smb network https network ipp network ipps| Does someone have any clue? Of course I played with usblp module (removed, loaded), no avail. Thanks, Zsolt
