I am in real fix and need your expertise to solve this problem. I have a desktop computer which is installed with Windows XP operating system. The computer is connected to HP 2100 printer. The problem which I am facing with the printer is that, whenever print command is given it prints all the garbage characters but it prints the test page perfectly. I need somebody to explain me why HP 2100 printer only prints test page properly and why cant it print other useful documents. Any help regarding the issue is more than appreciated. Thanks in advance.
