Same issue for me, also on photosmart 7450. I managed to get one test page out of the printer and that's it. What is happening is that the printer disappears from the usb channel. Why it does that I do not know but the computer really cannot communicate to the printer anymore when it is gone. I tried to plug it in on different usb ports but that does not resolve anything.
One other strange thing is that it always says "Pen cleaning in progress" just after switching it on and that status message does not go away. Note that I did install new cartridges with all these issues and was able to get 1 test page out which printed nicely. Another thing is the cartridge for color always indicates as not installed althoug it is and with the test page, it used the colors. I kicked out Windows but a bit too soon I believe... Desparate for a fix... me@Lapper:~$ lsusb Bus 002 Device 041: ID 03f0:b802 Hewlett-Packard PhotoSmart 7400 series Bus 002 Device 003: ID 046d:c03d Logitech, Inc.
