I am trying to use the printer functions. I could successfullly connect to a printer on my network and print the example given in printer_draw_rectangle() and print_draw_text()

But when I try to use printer_write() as below 
<?
   $handle = printer_open("printer");
   printer_write($handle, "Text to print");
   printer_close($handle);
?>     
I was expecting  "Text to Print" to be printed. 
Instead it gave me the error message

Warning: couldn't allocate the printerjob in c:\pathtohtdocs\test\print_1.php on line 3
line 3 corresponds to 
printer_write($handle, "Text to print");

PLS NOTE THAT THE printer_open("printer") STATEMENT WAS UNALTERED WHILE USING pinter_draw_tex() and printer_draw_rectangle() functions.
