Color output problem to a CMYK printer

I'm new here and this has probably been dealt with numerous times, but I have been unable to find it.  I have an image I imported from a pdf, it has a process color (magenta) and a couple of Pantone spot colors.  In one case the 2 pantone colors are used in a gradient fill of some text.  My first samples were off (I had not noticed but the buyer did) and now I have to print 36 copies and I can't hit the colors my monitor shows me.

I use CorelDraw X3, I have a Brother GT-541 Garment printer (CMYK), I have color management turned off and I have the design set as RGB.  The colors should be a sort of Pink to a Cerulean Blue,  and a purple, but I'm getting Red to a lighter Navy and a darker Barn Red. 

I thought maybe out of gamut colors (Illustrator said that- it also had the exact same problem).  Any ideas?  The buyer is picky or I would not be here.
