Tried the same file from an Ubuntu 12.04 install on a different machine and got the same result (printer hangs). Here's some more info: Printer completely frozen at this point and will not respond to any button pushing. Solution has been to remove and replace power cord, and restart printer. At this point it feeds the "stuck" page and is ready to print a new job. ==================== user@machine:~$ lsmod | grep usb usblp 17885 0 usb_storage 39646 0 ==================== user@machine:~$ tail -f /var/log/syslog Jul 18 14:12:19 kiertokone kernel: [17844.876051] usb 1-1: new high-speed USB device number 7 using ehci_hcd Jul 18 14:12:19 kiertokone kernel: [17845.014506] usblp0: USB Bidirectional printer dev 7 if 1 alt 0 proto 2 vid 0x04A9 pid 0x1723 Jul 18 14:12:19 kiertokone kernel: [17845.017155] scsi7 : usb-storage 1-1:1.2 Jul 18 14:12:20 kiertokone kernel: [17846.018665] scsi 7:0:0:0: Direct-Access Canon MP470 series 1030 PQ: 0 ANSI: 2 Jul 18 14:12:20 kiertokone kernel: [17846.025438] sd 7:0:0:0: Attached scsi generic sg2 type 0 Jul 18 14:12:20 kiertokone kernel: [17846.032328] sd 7:0:0:0: [sdb] Attached SCSI removable disk Jul 18 14:15:10 kiertokone kernel: [18015.950208] usblp0: removed Jul 18 14:16:05 kiertokone kernel: [18070.733277] usblp0: USB Bidirectional printer dev 7 if 1 alt 0 proto 2 vid 0x04A9 pid 0x1723 Jul 18 14:16:34 kiertokone kernel: [18099.966883] usb 1-1: USB disconnect, device number 7 Jul 18 14:16:34 kiertokone kernel: [18099.969470] usblp0: removed ###USB cable replaced Jul 18 14:17:00 kiertokone kernel: [18126.100259] usb 1-1: new high-speed USB device number 8 using ehci_hcd Jul 18 14:17:00 kiertokone kernel: [18126.239621] usblp0: USB Bidirectional printer dev 8 if 1 alt 0 proto 2 vid 0x04A9 pid 0x1723 Jul 18 14:17:00 kiertokone kernel: [18126.242179] scsi8 : usb-storage 1-1:1.2 Jul 18 14:17:01 kiertokone CRON[20108]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) Jul 18 14:17:01 kiertokone kernel: [18127.242538] scsi 8:0:0:0: Direct-Access Canon MP470 series 1030 PQ: 0 ANSI: 2 Jul 18 14:17:01 kiertokone kernel: [18127.249431] sd 8:0:0:0: Attached scsi generic sg2 type 0 Jul 18 14:17:01 kiertokone kernel: [18127.258917] sd 8:0:0:0: [sdb] Attached SCSI removable disk ###Calc job sent to printer?
