Printers

What is and what is not

Printers is not a lib for print drivers or cups. Printers is a simple lib for running "native" printing commands from unix (lp/lpstat) and windows (lpr/wmic) systems.

Printer can provide a list of printers available on the system and perform document printing.

Behavior

• printers::get_printers() -> Vec\

  Run lpstat or wmic -> Return a vector of available printers

• printers::print(Printer, &[u8]) -> Job

• printer.print(&[u8]) -> Job

  Save buffer as temporary file -> Request print of the temp file with lp or lpr

• printers::print_file(Printer, &str) -> Job

• printer.print_file(&str) -> Job > Request print of specific file with lp or lpr

Example

```rs use printers;

fn main() {

// Vector of system printers
let printers = printers::get_printers();

// Print directly in all printers
for printer in printers.clone() {

    let job1 = printer.print("42".as_bytes());
    let job2 = printer.print_file("/path/to/any.file");

    println!("{:?}", printer);
    println!("{:?}", job1);
    println!("{:?}", job2);
}

// Print with aux lib function (legacy)
printers::print(&printers[0], "42".as_bytes());
printers::print_file(&printers[1], "/path/to/any.file");

} ```

System Requiriments

Windows / LPD

For Windows is necessary turn on LPR and LPD running on localhost to perform lpr command to print

Unix / Cups

For Unix is necessary cups service running to perform lp command to print
