hello. My name is***** will assist you with your question.
You haven't provided much information here to go on, but if you are referring to printing from a Command line or printing to a file, and is file already exists, this would explained one reason for the system appending a one to the print name.
if not, and you're printing from a print dialog, then I don't know what you mean when you say that it "tags a print one". Can you please provide whatever additional information you can help clarify what exactly are trying to do and what exactly happens? For example what exactly the error is? Then I can give you an answer more tailored to your specific situation.
