This is weird. When I print a PDF file from my sp3, it will make 1 or 2 mistakes while printing. For example, it printed one page with the title at the top replaced by random letters and symbols like "!!"#$& (!)." The rest of the page printed perfectly. On another page, it left out 2 characters in the body of the document that almost went unnoticed. I copied the file to an older laptop and also an older desktop computer and both of those computers printed the same file perfectly, so I know the there is nothing wrong with the file. All 3 of the above mentioned computers are on the same wifi network. Then I went to a friends house with my sp3 and printed the same file on her wifi / printer and it made the same mistakes. As you can see, I have obviously isolated the problem to the SP3 since it made the same mistakes on 2 different wifi networks and 2 different printers and the same file printed okay on 2 other computers. Any ideas would be welcome. Thanks.
