Sending Escape codes to printer

[Hugh Myrie]

Given the following, how do I send escape codes to print?

for _, line := range lines {

fmt.Fprintf(p, "%s\r\n", line)

}

How do I send escape sequences using the above print command?

Below is a C# example:

output = Chr(&H1D) & "V" & Chr(66) & Chr(0);

I want to send the escape codes to a receipt printer to control the perform cetrain functions.

Some commands include:

ESC "J" 4  <--Feed paper 

 GS "!" 0x11  <-- change character size

Start here: https://golang.org/ref/spec#Rune_literals. Then read the next section about string literals and note that rune escape sequences are recognized inside double-quoted strings. For example, your feed paper command could be written "\033J\004" or "\x1bJ\x04". There are other ways, of course, to construct such strings that may be more readable by using constant declarations such as `const Esc '\x1b'`.
