Description:
------------
I use printer_draw_text() in a function that divides a string into multiple lines when printing.
the strange thing is that some lines are not printed.
The main problem is that when calling printer_draw_text() sometimes no data is printed, without any error message or warning.

Reproduce code:
---------------
reset($arr_words);
while(list($int_key, $str_value) = each($arr_words))
{	
  if($int_count + strlen($str_value) >= 35)
  {
    printer_draw_text($obj_printer, $str_temp, $int_x_pos_5, $int_y_pos);
    $int_y_pos += $int_y_step_small;
    $int_count = strlen($str_value) + 1;
    $str_temp = $str_value.' ';
    if($int_key == key($arr_words))
    {
      printer_draw_text($obj_printer, $str_temp, $int_x_pos_5, $int_y_pos);
    }
  }
  else
  {
    $str_temp .= $str_value.' ';
    $int_count += (strlen($str_value) + 1);
    if($int_key == key($arr_words))
    {
      printer_draw_text($obj_printer, $str_temp, $int_x_pos_5, $int_y_pos);
    }
  }
}


Expected result:
----------------
large string should be printed divided into strings of 35 characters max. Otherwise a new line should be started.

Actual result:
--------------
Not possible to show, but on printer some calls to printer_draw_text are not printed.
