The only other thing to remember is the buffer memory. The LC24-300 Colour contains memory which can be used as a print buffer (page 57) which must be cleared (“Clearing the buffer” on page 43) if a print job is to be halted. The SPC-8K also contains a buffer, which must also be cleared if you are to halt a print job successfully.
You clear the SPC-8K’S print buffer by pressing the but- ton recessed in the body of the SPC-8K.

The following information is provided for use if your computer does not have a standard 25-pin serial connector. If you computer does have a standard 25-pin serial connector, you can use a “straight-through” 25- pin cable.
If you need to use the SPC-8K with any other computer, you will either have to buy or make your own cable. If you are in doubt, show the chart below to your com- puter supplier or to friends who have experience with serial cables.
