How do I print two copies out of two different trays?

What model is it?  Perhaps you can setup a letterhead tray that would print the first page from one tray and rest of the pages from the other.  

If your invoices are usually one page of each color, this might work.  It depends on whether your printer supports letterhead or not.

It is a laserjret 3015dn with two trays

So if the printer supports cover pages you are able to control a print job that will create two pages with the same information but coming out of two different trays?

Yes.  I have a client with a Panasonic DP-C354 Laser and it has an option like that.  What we  do is set up three printers on each workstation for that printer.  On is "Panasonic Color" one is "Panasonic B&W" and the last is "Panasonic Letterhead".   When you select the last one, it pulls page one from tray 3 which has pre printed letterhead.  The rest of the pages print from tray 2 which is blank paper.  This happens automatically.  One job, two trays.

The obvious limitation is that the letterhead tray will only print on page one.  

to set a global preference, go to the control panel and choose printers and then preferences for the printer.  When you save it from there, it becomes permanent for the printer as opposed to when you print a job from word or something.  That just changes the preferences for the session.

I have a HP laserJet 3005p which I believe supports letterhead.  I will try this late today.

Thanks

"I don't believe any standard laser printer can be told to automatically  create two copies of each page of an incoming job, printing each copy on  paper selected from a different paper tray."

That's not what I was trying to say. I mean that if you send a 2 page job to the printer, page 1 can come from tray one and page 2 can come from tray 2.  

The limitation being, if you sent a 5 page job to the printer, only page 1 would come from tray 1 and pages 2-5 would come from tray 2.

So if your printer supports that, then yes, it can do that.  On the Panasonic and Lanier that I work on, its called "Cover page" in the prefs and you choose which tray it comes from.

So if her invoice is one page that needs to be printed on white with a copy on yellow, this would have worked for her.  I didn't see support for that on her model when I looked through her manual.

Bossman that is exactly what I need one job two copies but out of different trays..I called Xerox sales rep and she is looking into this as she never heard of a customer needing this type of job

Here are some screen shots from the Panasonic c354 preferences that show that feature.  Maybe your Xerox rep can use this to figure it our.

I'm still a bit confused as to what the requirement is!

The author wants "one job two copies but out of different trays" which (to  me) appears to mean:

(a) Job contains 'n' pages;
(b) Each page is to be printed once using paper from tray 'A';
(c) A copy of each page is also to be printed using paper from tray 'B'.

The driver feature which Bossman117 is refering to will not do this.
What it WILL do is to cause the FIRST page of each job to be printed on paper from tray 'A', with all subsequenet pages printed on paper from tray 'B'.
It will NOT automatically produce any page copies.
