Splitting text file

Kinda new to autoit. I have this situation where I need to take the print output from a dos program and split the pages apart so it will print properly. This is a 25+ year old program, running in DosBox. The issue is that when printing statements the next page will start on the first, and so on. I've tried different dos->windows printer type programs and none of them will split the pages apart properly. 

I had this working at one point but some changes in their system have removed that possibility. 

I believe a simple autoit script could do this. 

My thinking was something like this:

Read the text file - Easy

Split the pages - Eh 

Print the pages - 

It's been a while since I've done any coding but I can't figure out how to split the pages apart. Each page starts out "COMPANY NAME, INC". I can split around that but I lose that line or "COMPANY NAME, INC" depending on which method. 

Anyone have an idea on splitting?

I found this code

#include <File.au3>

Global $FileArray
$file = @ScriptDir & "\test.txt" ;"C:\SBT\Incoming\SBTFILE.txt"
$newfile = @ScriptDir & "\split-" ; "C:\SBT\Work\SBTFILE-"

_FileReadToArray($file, $FileArray)

$filecount = 1
$sNewFile_Text = ""

ProgressOn("Processing SBT File", "Reading The File...", "0 Lines")

For $i = 1 To $FileArray[0]

    If StringInStr($FileArray[$i], "****** END OF REPORT ******") Then
        ; We need to write the current file
        FileWrite($newfile & $filecount & ".txt", $sNewFile_Text & $FileArray[$i])
        ; And start a new one
        $filecount = $filecount + 1
        $sNewFile_Text = ""
    Else
        ; Add line to string
        $sNewFile_Text &= $FileArray[$i] & @CRLF
    EndIf

    $Percent = Int(($i / $FileArray[0]) * 100)
    ProgressSet($Percent, $Percent & " Percent Complete")

Next

ProgressSet(100, "Done", "Complete")
Sleep(1000)
ProgressOff()

And modified the END OF REPORT to match the string I am looking for but can't figure out how to make it split right before that line.  That code makes files like this

File 1:

COMPANY NAME etc

File 2 and so forth:

ADDRESS

** REST OF PAGE **

COMPANY NAME

Your help is appreciated.
