First many congratulations for your helpfull job about HP 2000C printer and Windows 7 !
I used a HP 2000C printer... untill i install Windows 7 64 bits (instead of XP). If i correctly understand, your solution works only with Windows 7 32 bits. Here is now, in 2014, a way to make this printer running with Windows 7 64 bits ?
