Old DOS accounting application to Print via Dot Matrix in WinXP

Hello, i have a very old DOS application that was made in 1992. It runs via DOS. I had a problem to run it in WinXP because it caused memmory overflow. I Used DOSbox and now it works fine. Now my problem is that it cannot print via the application to the Dot Matrix Printer that i Have. I installed the printer correctly, and via DOsBox if i enter : echo Mike >> PRN or echo Mike >> LPT1 then the printer works fine. Also through [login to view URL] (MS Editor) also prints fine. My problem is that it cannot print through the application. i attach the application MAT.ZIP. Just unzip it and run it. It is in GREEK but it doesn't matter. You can try if it prints by pressing the following buttons after runing it. 4 1 down 1 down 1 END (the key) it must send something to the printer. If it does you are OK.
