I have a Lexmark ink-jet printer at home and I have been using it for s few months now. I generally use it for small scale work at home with minor printing of documents which mainly consists Lemark Printing Symbols and it was working just fine. If you are trying to print a document in an unsupported format, it may cause the printer to produce symbols or garbled output. Convert the document to a different format or try printing a different file to see if the issue persists.
