I've been working on a desktop application built using .NET Framework 4.5 and C# as language. Requirement is that a printer will be connected on serial port, port settings will be provided by user through the application like port number, baud rate etc. etc.
When user hits a print button, it should directly print to the printer without showing a print dialogue.I've never done printing from desktop application and i've no idea how to achieve this.
- Should i have to code specific to driver of that printer?
- Or is there any generic way to send print instructions to printer connected to serial port?
- I can send normal string to serial port, but what if i need to do some formatting like drawing a table, how can i make a serial port printer printing a formatted table and values inside it .. for example a bill.
Any help would be greatly appreciated.
Thanks,Amit
