Incredibly disappointed

I purchased a dual tray HL-L5200DW that has a large dual tray setup w/wireless print function. I did this because I have a small notary business with a need to print bulk docs that vary size between legal and Letter size paper within the same print job.

In short, this app forces you to use a single paper size prior to the print job. This renders the app and the dual trays a pointless expense. Ive wasted a large amount of money on the printers ability to use separate paper feeds if it cant use them properly. Ive also essentially created the need for a laptop of some sort for it to properly recognize paper sizes within the same print job.

I find it hard to believe Brother thought this use case wouldnt come up for wireless/iOS users. Completely frustrated at a good companys limited capabilities and wasted money on my end.
