The T100MD+ COMM1 port can be configured with any baud rate from 1200 to 38,400 and 7 or 8 data bit, 1 or 2 stop bits, none, even or odd parity using the SETBAUD command. So it should be able to interface to practically any kind of RS232 serial printer. Most printers should support 9600,8,1,n format. You can change COMM1 to this format by executing SETBAUD 1,3.
If your printer cable is meant to connect directly to a PC (most are) then you have a female plug and you need a null modem (female to female) to interface to the PLC's COMM1 port. There may be a need to short the RTS/CTS or DTR/DSR together if your printer require handshaking.
