Setting the paper size of the paper in tray using PJL/PCL5

Question

Hi,

I am having trouble with a certain printer. I am unable to set the size of the paper in the manual feed tray, even though (I think) it should accept all sizes that would fit. Anyway, I've been trying to set the page size via the "& l # A" command to no avail. What I want to do is set it to custom and perhaps allow me to specify a value. Is there a PJL or PCL5 command I can use to set the size of the paper in a certain tray?

Thanks,
