For those who are still having problems with this there is a way round it, or at least there is with my HP PSC1410.
If you go to your start menu and look for the startup folder, in there you will probably find something starting with HP. I didnt write down what it was but its something along the lines of HP update or HP monitor. If you right click and delete it, it will stop the software loading at bootup that gives you the message to align the printer.
I should be noted however that if you do this you will not get warnings of when your cartridges are running out so you will have to do it the old fashioned way and replace them when it goes streaky.
