I've looked at that manual before posting, and it
does not have much
to work out from. All the names of the signals are different.
Ready is inverted between the two, I think. Both have the same basic
data transfer signals. Dataproducts has forms handling stuff that's
not in centronics.
Pinouts for both are in various googlable places, including:
http://www.hardwarebook.net/connector/parallel/centronics.html
http://www.hardwarebook.net/connector/parallel/dataproductsdsub50.html
http://www.hardwarebook.net/connector/parallel/decprinter.html
You should be able to compare what's in the LPV11 manual to these and
work out which are which. Then figure out the pin numbering schemes
used in the LPV11 manual.
