My old PC is running XP SP3 and connected to HP OfficeJect 4620 printer. I have to make 50 copies of a document for my classmates. The problem is that I was told to write my name and contact number on each copy, which I think will make me exhausted. Could you recommend me any software that will help me solve this problem?
If you already have the document in a word processor format you would be better off just adding a header with the same details.
Then just print out your document.
Alternatively you may be able to add a watermark via your printers settings dialog, (usually on the advanced tab), or for a really basic method - work out how many pages you are talking about and print just your name and contact details near the edge of every page then re-use the paper to print the documents.
For a real out of the box answer just get or make a rubber stamp and use that with an ink pad ...
