Scanning directly to the pdf will give you huge files because the whole 
page is then a rasterized image. You have to scan at or above 300 dpi 
for good image quality.

OTOH, scanning into a decent OCR program requires the ocr be familiar 
with the font, and that the source image be done at 600+ dpi.  Then the 
text must be read, and obvious errors fixed.

Then, from that text file, a pdf thats about 5% of the size of scanning 
direct can be made. But probably losing any fancy calligraphy or images, 
depending on the OCR. I've little experience, but it would make sense 
for the OCR to give up and save the image once its obvious it does not 
recognize the character. That switch should be at an error level 
settable when the page image is fed to the OCR. 

Method 1 is quite a bit faster, but the pdf's will be huge if the fine 
details are to be adequately preserved.

And just to see if I know what I'm talking about, I just scanned one side 
of an Orkin bill. its 3 color, black/white/red. At 600 dpi, the page 
scan was 200 megabytes, and the resultant ocr wasn't readable, way too 
many mistakes. Text looked like a non-english language.
So I killed that image and am now loading one at 2400 dpi. With 8GB of 
ram to play in, I think kooka, the driver behind all this has crashed. 
Its had 1 core at 100% for 9 minutes and its reporting a tmp of 78C for 
something, which when I look it upin gkrellm, is the temp of my gfx 
card. I was able to kill the process, but with a 32 bit install, the 
data is just too darned big for this machine. The gfx card is working 
but still too hot, the fan has died. I have a spare ran so with this I'l 
shaddup and fix it.
