lp behaves differently if you cat a file to it

One of my users has notcied the following behaviour

The CUPS lp command behaves differently for these two commands:

   lp -d myprinter filename
   cat filename | lp -d myprinter

In the top command the file prints just fine on A4 paper to the printer (HP laser 4100).

When the second command is used the printer tries to print from a different tray and asks for letter size paper to be used.

How can I stop this from happening ?

It needs to work the same both ways as some very expensive EDA software (Cadence) prints using the second command
