I want to send print to the printer port in vb.net character by character (one character at a time ), not the whole file.
the purpose is like

for i = 1 to 15

next
value of i shloud be transferred to the printer port at each execution of the FOR LOOP:
the value of i of the for loop that is executed 15 times should be printed.
print should be in this format:
1 2 3 4 5
6 7 8 9 10
11 12 13 14 15 (means value of i)

any body help me please. i need it urgently.
