PRESCRIBE - Odd & Even printing using different Trays

[Swift]

I have a customer who use an Accounting Software to print their Tax Invoices.
The Tax Invoices come in variable pages & users are printing direct to the TASKalfa 3050ci.
Customer requesting to print Odd pages on Tray 1 & Even pages on Tray 2.

Anyone can help me on this area?

The KX driver allows you to do this; on the Advanced tab you will find Prologue / Epilogue. You would need to set the emulation to PCL5 and create two Prescribe text files, one for odd, one for even pages and then define the behavior in the print driver. The text file for pulling from tray one would be something like:
!R! PSRC 1;EXIT;
