I wrote in error:

"It takes two samples to resolve a line -- one to see the line, the other to see the space between the lines, so that's only 1270 spi (samples per inch)."

Sigh. I did the math backwards. It does take two pixels to resolve a line, not a half a pixel! 100 lpmm requires 4900 samples per inch to resolve.
