问题 Does anybody have any idea about the differences between barcode fonts (used as a font in reports) and fonts that are printed directly from a barcode printer? Why should we put a star before and after the barcode font? It's my understanding that we don't need that when we use a barcode printer... why not? 回答1: The star character is part of the specification for Code 39. It is used as a delimiter for the barcode itself. Barcode readers will not recognize the code if the stars are not present.

问题 How can I print in Silverlight 4 without a print dialog showing all printers. Many people say it not possible but they always talk when the app is running in the web browser. In this case I'm out of browser and with elevated trust. Any suggestions? 回答1: Even with elevated trust, you are still going to have to deal with the print dialog using the print API.
