Sorry but, as I said and I quote from the link you kindly provided,
"In practice, SPI and PPI are often used interchangeably. DPI is
frequently used in place of one or both terms. However, even if you call
it DPI, remember that each dot or "unit of measure" behaves differently
depending on whether it is a scanner (or scanned image), a monitor (or
on-screen image), or a printer (or printed image)."
