I am using oracle forms 6i and want to print my POS invoice on thermal printer. I already have "continuous" printing directly on dot matrix printer where I am opening my LPT port through text_io package and generating invoice as per the requirement.
Now, the customer wants to generate the invoice on a thermal printer. Suppose, I want to print 9 lines on printer page then after 9 lines printing must be stop.
My code is as follows :
declare
pvf_file text_io.file_type;
vs_prn_port varchar2(128) :='LPT1';
begin
lpt1:= Text_IO.Fopen(vs_prn_port,'a');
text_io.put_line('This is a first line.' );
text_io.fclose(lpt1);
end;
Please guide me if you have any thoughts.
