   6. Check whether the printer gets correctly detected by the USB subsystem and determine its USB vendor/product IDs and the USB bus and device addresses: <<BR>> {{{$ lsusb}}} <<BR>> Note: The USB bus and device addresses change if you turn off or unplug the printer. Please re-run this command if needed.
   7. Check whether the device files for the printer get created and the ownerships ("root lp") and permissions (non-HP: "crw-rw-r--", HP: "crw-rw-r--+") correctly set: <<BR>> {{{$ ls -l /dev/usb/lp* /dev/bus/usb/*/*}}}
   8. Determine the printer's device ID strings: <<BR>> {{{$ sudo usb_printerid /dev/usb/lp0}}} <<BR>> {{{$ sudo usb_printerid /dev/usb/lp1}}} <<BR>> {{{...}}} <<BR>> For HP printers also use <<BR>> {{{$ hp-info -i}}} <<BR>> and choose the printer with the problem from the text menu, then copy the "deviceid" entry from the output (can be several lines).
-  9. For HP printers: Check whether HPLIP connects to them: <<BR>> {{{$ hp-makeuri <Bus>:<Device>}}} <<BR>> Replace "<Bus>" and "<Device>" by the bus and device numbers from the "lsusb" output (not vendor and product ID). The numbers must be supplied with three digits, zero-padded from the left, like "008:015".
+  9. For HP printers: Check that you have the latest version of HPLIP and whether HPLIP connects to them: <<BR>> {{{$ hp-makeuri <Bus>:<Device>}}} <<BR>> Replace "<Bus>" and "<Device>" by the bus and device numbers from the "lsusb" output (not vendor and product ID). The numbers must be supplied with three digits, zero-padded from the left, like "008:015". (More information from [[http://hplipopensource.com/]].)
   10. Find out if your printer gets detected by CUPS: <<BR>> {{{$ lpinfo -v}}}
   11. Attach the output of the above commands to the bug report.
