Class LpstatPrinter

java.lang.Object

oshi.hardware.common.AbstractPrinter

oshi.hardware.common.platform.unix.CupsPrinter

oshi.hardware.common.platform.unix.LpstatPrinter

All Implemented Interfaces:

Printer

@Immutable
public final class LpstatPrinter
extends CupsPrinter

Native-free CUPS printer implementation. Queries printers via the lpstat command rather than libcups, so it works without JNA or FFM native access. Used by platforms whose hardware abstraction layer lives entirely in oshi-common (currently NetBSD).
