I have an Epson POS printer which support printing via my COM port using ESC/POS. This all works well in my c# app. I have used Epson's BMP converter tool to convert a bmp file to a binary file which can be sent directly to the printer.
How would I get my c# app to send this binary file straight to COM1?
I am familiar with the basic sp.Write("lalala") and sp.Writeline("lalala") commands.
The binary file is only 4kb in size so do I really need a binarystreamer? Can I not just do something like fopen(logo.dat,br) ??
Your help is appreciated thanks
