Hp laserjet 1300 prints extra blank page

Before you get a better answer to me , I hope you would have told us if you are the first person that used it so that we can know if this problem started from the initial point or at the middle time of using the printer

1) Did you add additional memory to the Printer?, if Yes remove and try back.
2) Try you use this printer in another PC
3) Look for HP1300 printer software.
4) It may be a mechanism/paper carriage error which can not be corrected by software unless you change mechanism/paper carriage.
