printing on POS printer from Ora Forms

I need a solution about printing from Ora Forms(6i) to POS printer(3- tier architecture,AS on Unix).
You can see code bellow which is working on client-server architecture(Windows).
But, problem is that we moved to 3-tier(AS on Unix) and now I need a solution of how to implement this.
May I register POS printers on Unix(AS) as network printers and make a LOV of printers so users can choose POS they want to print.Or is there any other solution.

Tnx in advance,

DECLARE

	OUT_FILE 		TEXT_IO.FILE_TYPE;
  	linebuf   		VARCHAR2(255);
  	cCUT_PAPER		VARCHAR2(10) := CHR(27)||'i';
  	cCode_Page varchar2(200) := CHR(94)||CHR(93);
        cPRINTER_PORT varchar2(10) := 'LPT1';--or it can be network
printer ex. '\\printers\pos1'
	CURSOR C1 IS
	SELECT some_col
	FROM some_tbl;
  	v1 c1%ROWTYPE;
begin
        OUT_file := TEXT_IO.FOPEN(cPRINTER_PORT, 'W');
	open c1;
	fetch c1 into v1;
	close c1;

        linebuf := 'XXXX';
        TEXT_IO.PUT_LINE(OUT_file, linebuf);
        linebuf := 'some additional text';
        TEXT_IO.PUT_LINE(OUT_file, linebuf);

	TEXT_IO.PUT(OUT_file, cCUT_PAPER);
	TEXT_IO.FCLOSE(OUT_file);
