redirecting print job by size

I have two types of files that I need to send to different printers. I'm able to differentiate the files by their size. I want to send the smaller file to one printer and the bigger one to another. I'm trying to figure out how to script this but I'm getting syntax errors. I should be able to figure it but if somebody just knows the answer it'll save me time. Thank you in advance for any help.

I figured it out. I just used the conditional settings. Thanks anyways
