Xetec's Serial Printer Interfaces (SPI and SPI+) are designed to allow the Commodore VIC 20 or C-64 to print with any parallel printer that is Centronics compatible. They are primarily intended as a substitute for the
Commodore 1525 printer, and therefore can be configured to make your printer work similarly. They have special functions, however, which the 1525 cannot perform. If you plan to make use of these features, a
thorough reading of this manual is suggested. Otherwise, a skim will probably get you up and runnIng .
