Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I'm sorry to hear about the problem, it must be quite frustrating. I hope I can help with it.
What security info did you put into your printer? please explain.
Also, what computer do you have please? a Windows PC, or an Apple computer?
I'm not sure yet what your question involves, so I cannot yet say what is needed. It sounds as if your keyboard, or typing on the computer, is quite slow... is it ?
I am not sure that security information printed out on the printer would make your computer slow. I think that is likely to be a problem on the computer. Can you tell me, what was done on the computer, or to the computer, recently, that might have affected it to make it slower? if you're not sure, just guess, and I will help sort it out for you.
