[alt-photo] Mac, Windows, Epson

[jusdado]

Hi all,
on my new Mac, I installed a program that emulates "windows" to print 
negatives with my Epson. Now I can access all drivers for my Epson 
printer. So far, Ok. When I print a 19x19cm negative. focused on 
transparency A4 (21x29, 7cm.), the result is a reduced image 15x15cm., 
trimmed and in the upper left corner of transparency.
Why not print a 19x19cm.?, Why not print centered on transparency?. I 
think after I bought my Mac, I'm going crazy.
Thanks and sorry for my English text translated by computer.
