Easy-photo Printing W/canon Pixma Ip 3000

[red girl]

i am having problems deleting unwanted pics in easy-photo..all my rejects from iphoto turn up there...and i can't understand the order that they arrive in easy-photo from iphoto..i'm using easy-photo to print because the borderless in iphoto isn't completely borderless..and many times the color is truer..even though i love every other feature of iphoto.also,how do i delete all the worked on copies of pics in iphoto..the stored ones? thanks a million....redgirl
