There is no pin 18 to get a centronics-compatible pin numbering. Ie. although the CPC uses * Note: Despite of using a '''34pin''' edge connector, the pins are numbered as on Amstrad used a '''36pin''' centronics Centronics-style pin numbering. Pin 18 and Pin 36 do not exist on the 34pin edge connector.
* As shown above Pin9 is wired to GND (instead of Data 7), for upgrading, : see [[8bit Printer Ports]].

All other CPC+ and [[KC Compact]] printer ports differ on Pin 16,17. Also, Pin 9 is controlled differently on software side (see [[8bit Printer Ports]]). And, Pin 1-8 are bi-directional on the KC Compact. == Aleste Printer Port ==The [[Aleste 520EX]] uses two 7pin DIN female connectors: Pin X5.B X5.A X5.B X5.A 1 D4 D0 __ __ __ __ 2 COMMON GND / - \ / - \ 3 D7 D3 |(7) (6)| |7 6| 4 D5 D1 |3 1| |3 1| 5 D6 D2 \5_2_4/ \5_2_4/ 6 UCC STROBE 7 UCC BUSY Shield GND GND* According to the schematics, X5.B is only 5pin. But according to component map and all existing photos, both connectors are 7pin. According to the Russian User Manual, the two extra pins are NUCC (+5V).* COMMON is /Joystick1 select, there is no purpose specified for it being on the printer port. It could be ''possibly'' used as /AutoLF, /Select, or /Init (though the latter one would reset the printer on every keyboard scanning).* Caution: The Aleste uses different I/CO Ports than CPCs to access the Printer.
