We have recently procured a Brother HL-6050 printer.
In UNIX (HP-UX) we have a program that requires a single program output to be printed on A5 (optional tray) whereas the default be A4 (tray 1).
If I place the following line in the header of the output print header of the program,
Then the program prints from the optional tray (currently with A4 in it).
So far so good....
Now I replace the A4 paper in the optional tray with A5 paper and run exactly the same program. Now instead of using the optional tray as the source it starts to use tray 1 again (the wrong tray).
Any ideas much appreciated!
