According to specifications published by HP, this scanner's hardware and 
optical resolution is 1200x1200 dpi.  I just called HP tech support to 
confirm this and was told this is correct and that, further, there are 
"4 pixels per dot", meaning that the scanner handles both color and B/W 
at that resolution.  So I don't know why scanimage would report that 
300dpi is the maximum resolution.
