Member Function Documentation

forceFormFeed()

virtual void openmsx::PrinterCore::forceFormFeed ( )

protectedpure virtual

Implemented in openmsx::ImagePrinter.

Referenced by unplugHelper().

getStatus()

bool openmsx::PrinterCore::getStatus ( EmuTime::param  time )

overridevirtual

Returns the STATUS signal: false = low = ready, true = high = not ready.

Implements openmsx::PrinterPortDevice.

Definition at line 54 of file Printer.cc.

plugHelper()

void openmsx::PrinterCore::plugHelper ( Connector &  connector, EmuTime::param  time  )

overridevirtual

Implements openmsx::Pluggable.

Definition at line 73 of file Printer.cc.

setStrobe()

void openmsx::PrinterCore::setStrobe ( bool  strobe, EmuTime::param  time  )

overridevirtual

Sets the strobe signal: false = low, true = high.

Normal high, a short pulse (low, high) means data is valid.

Implements openmsx::PrinterPortDevice.

Definition at line 59 of file Printer.cc.

References write().

unplugHelper()

void openmsx::PrinterCore::unplugHelper ( EmuTime::param  time )

overridevirtual

Implements openmsx::Pluggable.

Definition at line 78 of file Printer.cc.

References forceFormFeed().

write()

virtual void openmsx::PrinterCore::write ( uint8_t  data )

protectedpure virtual

Implemented in openmsx::ImagePrinter.

Referenced by setStrobe().

writeData()

void openmsx::PrinterCore::writeData ( uint8_t  data, EmuTime::param  time  )

overridevirtual

Sets the data signals.

Always use strobe to see whether data is valid. As an optimization, this method might not be called when the new data is the same as the previous data.

Implements openmsx::PrinterPortDevice.
