Status in hplip package in Ubuntu: Incomplete Bug description: My HP photosmart 7450 printer has been showing some communication problems since using Hardy. Prior to this, I've been running Debian stable on exactly the same hardware without any printer problems. The symptoms are: printer is detected as photosmart 7400 & appears to install correctly. I can sometimes initially print one or two pages, then it locks up completely, I get a pop-up notice on the top panel about printer supplies low (although it isn't). At this point, the printer firmware appears to have hung - it doesn't respond to front-panel button presses & the only way to get it to respond is to pull the power supply for a few seconds. On reconnecting, it sometimes prints, sometimes doesn't. I've tried uninstalling the hplip package and installing the latest version (2.8.5) from the hp website. It didn't make any difference, the symptoms are unchanged. It looks like there's another user with the same problem: http://ubuntuforums.org/showthread.php?t=809469&highlight=photosmart+7450 Following the advice from the debugging printer problems page: mike@badger:~$ lsmod |grep usb usb_storage 73664 0 libusual 19108 1 usb_storage usblp 15872 0 usbhid 31872 0 hid 38784 1 usbhid usbcore 146028 8 usb_storage,libusual,usblp,usbhid,ehci_hcd,uhci_hcd scsi_mod 151436 5 usb_storage,sg,sr_mod,sd_mod,libata mike@badger:~$ tail -f /var/log/messages Jun 20 20:24:37 badger kernel: [ 476.217222] scsi 2:0:0:0: [sdb] Sense not available.
