An A320 crew was provided a maintenance document that had been printed out of sequence. The document as printed would have led them to apply A319 rudder trim test limits to their A320.

Narrative:
ACARS printed maintenance flight release danger. Dispatched with a number two rudder trim system inoperative. There is a flight crew system test procedure required before each flight with numerous steps. There are different procedures for the A319 than the A320 aircraft with different values required as trim limits. The safety issue is with the way the ACARS prints the maintenance flight release. Our maintenance flight release was four pages long but printed in a one; two; four; three order thus mixing the procedural steps and we inadvertently continued the procedure for our A320 on the page that was intended for the A319. So the rudder limit of 20 left/right showing on the test (and correct for the A320) read as a failure for the 319 page (which requires 25 left/right). I noticed as maintenance was running their test that their paperwork showed only requiring 20 left/right. I relooked at the maintenance flight release and was able to deduce that the pages had been printed out of order leading us to look for the wrong limits during the test. A reprinted maintenance flight release had the exact same page order one; two; four; three. This is an issue that could absolutely affect the safety of flight and procedures. This needs to be fixed.
