Most functions are working with 7bit 7 bit ports, but - although it's Amstrad's official CPC printer, some functions are working only with 8bit 8 bit ports. Features that won't work perfectly with 7bit 7 bit ports:
* '''Graphics''' - The 9-pin graphics command is more or less unusable. The 8-pin graphics command can be used, though with only 7-pins being accessible; the line-feed rate must be set to 7/72 inch accordingly. Using only 7-pins does slightly increase printing duration, and (since more passes are needed) reduces lifetime of the print-head and ink-ribbon.
