[Javi]

Hello, i use python 2.5,  and wx, i'm trying to print a bitmap with 
transparency background  but it doesnt print right,  i just get a 
preview right but when i printed it, bitmap transparency background  is 
printed on black. I dont know why , but i need to print it right. All 
help will be welcome. Thanks.

P.D: i tried to print the wxpython demo 2.8 and  it happens the same, 
transparency background is printed on black.
