rather than shorting pins on the parallel port, i'd disable the printer by patching the executable file - change "prn" to "nul". "nul" is dos' null device - i.e. the bit-bucket, and is sometimes useful. for example, if i want to make sure that a floppy is readable\ i do the following: copy/v a:\*.* nul: terrell

Copy cannot verify data written to the null device, or any other character device. The verify is a dummy read after write; data is not stored in memory and not compared.
