An alternate method to using a printer with a Centronics port is purchase a printer which can read a compact flash card. Then you can save your pictures to TPS2000 compact flash card then print them direct from the printer, no cable required. The only requirement for the printer is that it recognizes one of the graphics formats which is produced by the scope. These are BMP, PCX, TIFF, RLE, and EPSimage. This allows you to print the pictures and also have an electronic record of the screen shot if needed.
