Adobe reader printing Pdf sequentially windows 10

My client is having problem since getting his new pc where he goes to print a batch of design drawings (all ordered and numbered) via windows explorer (dragging and dropping into print queue) and now the pdf files come out in a seemingly random order.

Is there a way to accomplish this? I've already tried changing the spool options on the Konica Minolta c224 they utilize. to only print the job after everything has spooled.

I realize I may have to advise the client to purchase Adobe DC Standard and setup an action, javascript to cycle through this.

But what's the most efficient and or cost effective way to accomplish this with Adobe Reader DC and Windows 10 for printing ~50 sequential pdf files .

I've already determined there is no rhyme or reason to the order they are printing out (all files in Windows explorer are sequential by file and unit name) and they do not print out in any order of file size (larger files print between smaller ones etc).
