This is my sister's computer hence the 'sexysue' ;) After recently upgrading to Jaunty I've noticed strange behaviour esp with in /var/log. Switching on the printer (HP Officejet 6310) gives me this in /var/log/kern.log Jun 15 09:34:41 sexysue kernel: [ 2176.060051] usb 1-5: new high speed USB device using ehci_hcd and address 3 Jun 15 09:34:41 sexysue kernel: [ 2176.219858] usb 1-5: configuration #1 chosen from 1 choice Jun 15 09:34:41 sexysue kernel: [ 2176.245616] Initializing USB Mass Storage driver...

The thing is, the printer starts to print, it prints the headers from the email (that's what I tried to print) but then just stops wihout printing the body of the mail; and then the log file gets hit. Any ideas from anyone? Google throws up nothing. Printing from OO is fine and have just succesfully printed the orignal email without the errors. This is very strange and I'm scared she'll run out of partition space if this happens when I'm not here .... which will likely be the case. CIA -Ants -- 100% naturally selected. 0% designed.
