Printer Core

printer-core provides the main multiplatform printing API.

API

Printer

Main interface used by applications:

interface Printer {
    suspend fun print(filePath: String)
    suspend fun print(imageBitmap: ImageBitmap)
}

Usage

1. Print an existing file

printer.print("/path/to/document.pdf") // or any other file type

2. Print a ImageBitmap

printer.print(imageBitmap)

Internally, the image is encoded into a temporary BMP file, printed via the platform, and then removed.

Creating a Printer instance

Use the PrinterImpl class to create a multiplatform printer instance, passing the platform-specific PlatformPrinter implementation as a parameter. In the following example, we use Koin for dependency injection:

// commonMain
single<Printer> {
    PrinterImpl(
        platformPrinter = instance(),
    )
}

// androidMain
single<PlatformPrinter> {
    AndroidPrinter(context = androidContext())
}

// iosMain
single<PlatformPrinter> { IosPrinter() }

// desktopMain
single<PlatformPrinter> { DesktopPrinter() }
