Printing in HP Laserjet 1020

My oe of customer has A PC Celeron 1.7 GHz, with Windows 98 OS, we installed a new HP Lasejet 1010 (USB Interface). Printer is installed but the problem is when we give the command to print (from any softwares or test page), it print but if we give second print command it won’t work, because the first print command is not clear up from the spool. Any troubleshooting??
