Nauman,
please clarify a little about what you're trying to do. If you mean 'can I send something from the S7-200 to a printer using a serial-to-parallel converter', then you skip one step. The interface of the S7-200 is NOT RS232, but RS485. So, you have to convert from RS485 to RS232 first. Fortunately, tis can be done with the PC/PPI cable you also need to program the S7-200. But the conversion is not enough. You also have to program the S7-200 to send something to the printer.
If you're question was to inquire if it was possible to list the program without using a computer, then the answer is no.
Kind regards,
