Creating labels with TCPDF

[eluser]smash120[/eluser]
I am creating a project which will require me to print lables which will be used for prescriptions. The data going into the label will be coming from a database. I just want to know how would I use TCPDF to make prescription type label in with a certain height and width. This is the first time I have tried something like this and I am new to TCPDF so any help is appreciated. Thanks in advanced

the bit of code below might help (or hinder :-) )
me amateur so code quality not great but works

Code:

// this uses tcpdf
//sample output is at http://ecoland.com/cidemo/pdfdemo.bmp
// first is a general purpose routine
// then comes an example on how to use

//1. this is a general purpose table print routine in a helper file
public function print_table($title,$cols,$data,$autoadjustcols = true,

  $mrg = $this->getMargins();
  $btmline = $dims['hk']-$mrg['top']; // pagelength
  if ($autoadjustcols){
   $w = 0;
   for ($i=0;$i<count($cols);$i++) $w += $cols[$i][1];
   $delta = ($dims['wk']-$mrg['left']-$mrg['right']-$w); // excess/deficit
   for ($i=0;$i<count($cols);$i++) $cols[$i][1] = ($cols[$i][1]*($w+$delta)/$w);
  }
  if ($title != ''){

      }
