That is the standard, but the DB25 to DB25 is available.
I get them from Digi-Key in the Assmann brand, their part numbers are :
IEEE-1284 cables DK part # AE9861 (1.8 M)
IEEE-1284 cables DK part # AE1374 (3 M)

The control signals MUST be twisted pair for the EPP mode to work 
reliably.  I have made some
special-purpose cables where ALL signals are individual twisted pairs, 
and they work fine,
but are a big hassle to make.  The "extension" cables have female 
standoffs on one end so
that the connector jackscrews can lock into them.  The part numbers I 
give above have
jackscrews on both ends, and are intended to go from PC parallel port to 
equipment on
the other end.  I can't say if Mesa uses the same connector polarity as 
my products do.
But these cables above are male DB25 on one end and female DB25 on the 
other.
