i checked the port and it is set to epp
excuse me if i ramble a bit
i create a file with one word 'hello' followed by a newline and a carriage return
the content of the file in hex is 68 65 6C 6C 6F 0A 0C
if i print the file with cat file > /dev/lp0 i get "helloJL"
capital J is 0x0a plus 0x40, capital L is 0x0c plus 0x40
0x0a and 0x0c are control characters
where and why are they being converted to printable characters
