not printing from network

I HAVE ONE PRINTER OF HP LJ 1020PLUS WHICH IS INSTALLED IN COMP1 & IT’S WORKING FINE ON THIS COMP1. I SHARED THIS PRINTER WITH COMP2 IT’S INSTALLED OK.BUT IT’S NOT PRINT FROM COMP2. IF I RESTART MY COMP1 & GAVE COMMAND FROM COMP2 IT’S COMES OK. IF ANY PRINT GAVE FROM COMP1 AFTER THAT I PRINT FROM COMP2 IT’S NOT PRINT.

FOR THAT ISSUE I REINSTALLED ALL DRIVER.
BOTH COMP HAVE WIN XP WITH SP2.
PRINTER CONNECTED WITH USB.

KINDLY REPLY ME.
