The Printer Port in the [[KC Compact]] is fully compatible with the CPCs Printer Port, and includes some additional features:
* Port EFxxh is CIO Port A, by default configured as Output, with inverted polarity on bit7 (same as on CPC). However, CIO Port A could be reprogrammed by software (for example: making it an Input, or disabling the bit7 inversion)
* The 8th Printer bit connects to Bit5 of PIO PPI Port C (same as the Happy Computer [[8bit Printer Ports|8bit Printer Port]] mod)
* The "TEST" Feature of the KC Compact BIOS allows to boot the computer remotely via some kind of "network" connection, which connects to some of the CIO Port A signals
