AbstractdisconnectDisconnect from printer port.
Calls each of the listeners registered for a given event.
Return an array listing the events for which the emitter has registered listeners.
Fetches printer information and stores it.
Get printer capabilities based on the printer model. Model library is hardcoded.
Get the stored information about the printer.
Determine print task version if any.
ProtectedinitialSend "connect" packet and fetch the protocol version.
AbstractisCheck if the client is connected.
Checks if the heartbeat timer has been started.

Return the listeners registered for a given event.

Packet object.
PrintError when ResponseCommandId.In_PrintError or ResponseCommandId.In_NotSupported received.

Enable some debug information logging.
Set interval for startHeartbeat.
Heartbeat interval, default is 1000ms
Set the interval between packets in milliseconds.
Starts the heartbeat timer, "heartbeat" is emitted after packet received.
If you need to change interval, call setHeartbeatInterval before.
Stops the heartbeat by clearing the interval timer.
Send wait for response for timeoutMs milliseconds.
If ids is set, it will wait for packet with this command ids.
Packet object.
PrintError when ResponseCommandId.In_PrintError or ResponseCommandId.In_NotSupported received and catchErrorPackets is true.
Abstract class representing a client with common functionality for interacting with a printer. Hardware interface must be defined after extending this class.
