Grayscale images

I am running PH5 on a PC with PM7 as the final before outputting to Brother HL2400C Color laser in mono.

I have managed to get a grayscale image in PH5 to have a screen of 53/45 and print the image out with PH5 picking up the dots as I would like it to.

Try as I might I can not place the image in to PM7 and get it to pick up the screen on output to the laser.

NEED HELP FAST

Saving the grayscale image as a Photoshop .EPS will preserve your linescreen preferences. include transfer functions

Thansk for your feed back. I have tried saving in photoshop eps. Even completing the dialouge box that comes up asking to transfer screen and function. With no difference. Is it something I am doing wrong before this stage or after it?????

I can print the image from photoshop with the screen but not from PM7 once I place it. Should I "INSERT OBJECT" rather then place????
