I have never used it with printer, but in general you could use any USB to RS-232 cable, bought by the local PC accessories shop.kdg007 said:is there any drivers i can use for printer port side which converts rs-232 to usb levels ?
.. what are the complications ?
i want to know whether it can be possible to do rs-232 to usb ...
yes,its an usb interface problem.Like i said,i need to figure out conversion levels . the blure cable already converts the usb to rs-232 levels,but if i convert it back ,will it work the same ?Curiously, you are only talking about cables, although it's basically an USB device interface problem. Which USB devices do you want to access from which application through which USB driver? "USB to RS-232" sounds like an serial port adapter (e.g. FTDI or similar chip). Replacing it by an USB cable requires an USB capable device, e.g. a printer. But you didn't mention a specific USB device.
No way. You would need an USB host to drive the printer. The only reasonable way is to connect the USB printer to the computer's USB port. Unfortunately, a windows printer isn't accessible as a serial port. The windows printer interface is designed to provide graphic printing capabilties. It does also allow simple character printing but not so straightforward as a serial port.the blure cable already converts the usb to rs-232 levels,but if i convert it back ,will it work the same ?
I can't understand why you insist on the old cable, just use the proper cable for your case.kdg007 said:hmm... it sounds impossible to use this cable.Is any slight possible way to utilize this cable to printer ? maybe a debug circuit ?
I try different things to learn more. i could able to got more info into this issue.RS-232 creates virtual COM ports, but you need the printer to be recognized by windows as a USB device with an ID, so RS-232 cable is not suitable for this purpose.
