Features\r\n\r\nWith this printer cable , you can still use your older parallel printers with your newer computer, eliminating the need for costly and time-consuming equipment upgrades. \r\n\r\nIt converts a printer's 36-pin parallel port for use with a USB port on a Desktop or Laptop Computer. The USB interface provides a much faster data transfer rate than a standard parallel port, \r\nthereby reducing the time waiting for a print job to be sent to your printer. \r\n\r\nIf you have multiple printers, you can eliminate the need for a switch box by connecting each printer to a USB port.\r\n\r\nImportant Note: This cord is only compatible with 36-pin parallel ports. There is 25 pin and 36 pin parallel port so please check the pins of your printer before you order. \r\nSomehow windows 10 is not compatible with some parallel printer driver, you can find that a lot of people posted the same problem on windows website. So we do not recommend the cable if you use it \r\n\r\n \r\n\r\nSpecification \r\n\r\n\r\n\t

In the old days of personal computers, one of the primary connections available was the RS-232 serial port. Apart from the parallel port, it was the primary means to connect an external device. The connector was reduced from a 25-pin connector to a 9-pin connector, but RS-232 ports remained present on every computer for many years. Built-in RS-232 ports featured direct mapping to memory and worked at a high priority. Data practically flowed directly to and from the software that was accessing the serial port.
In 1996, the Universal Serial Bus (USB) standard was introduced as a replacement for the serial connector and other connector types that were typically found on the back of computers. The USB provided smaller connectors and more data throughput than the serial and parallel interfaces it replaced.
USB devices have high throughput, but they use a shared data bus. Data is wrapped up and transferred in packets. To handle the packets and move data in and out of the program accessing the USB device, a software driver is needed. The software driver sits between the hardware and the computer program you are using, and it must be installed and working correctly.
For USB to RS-232 chips, there are two primary manufacturers: Prolific and FTDI. Because off-brand chips with poor drivers are unreliable, Campbell Scientific recommends and currently sells a cable using an FTDI chip (part number 17394). We chose this cable because it uses a chip that has a certified driver available on Windows Update. (The older cables were silver in color and did not have a driver available for Windows beyond version 7.)
I have an issue where my prolific USB to Serial adapter stopped being detected as 'n "Ports (Com & LPT)" device. It keeps on detecting it is a " USB Composite" device, even after installing the correct Windows drivers downloaded directly from the manufacturer's website. Uninstalling it and reinstalling it doesn't help.
I get the same result on another computer also running Windows 10. It simply refuses to recognize the adapter as a USB to Serial device anymore and keeps on detecting it as a "USB Composite" device as soon as you plug it in after uninstalling it and restarting Windows. Windows also claims that it finds no better driver than the one currently installed when doing a driver search, even after installing the manufacturer drivers.
Hi,
I'm facing a weird problem with my USB to serial-adapter. The adapter has a Prolific-2303 chipset. The COM port is not getting detected by the Windows 7 laptop.
I've installed the drivers and restarted the computer after installing the drivers.
I've run the driver update from the device manager and updated the drivers.
I also tried to install the COM port manually from the device manager.
I checked the adapter by connecting it to another desktop computer and the COM port is getting detected.
I have a few handheld radios that I need to update the frequencies and when I connect to the USB, it fails to connect. In device manager and Ports it says - "Please install corresponding PL2303 driver to support Windows 11 and further OS"
There is a working driver at _id=225&pcid=41, a bit down the page listed as "DCHU (for PC Vendors)". Getting it installed is a bit tricky, it seems. What I did is this:
First install the downloaded driver by unpacking the zip file and "pnputil /add-driver *.inf /subdirs /install" (the /install is probably not necessary) from the extracted "Win11_DCHU" directory. It will add the two driver packages to the driver store and tell you what oemXY.inf files it has assigned to them.
Then "pnputil /enum-drivers", and in the output look for Prolific drivers other than the ones from the previous step. I had only one other entry, a "ser2pl.inf" version "09/16/2021 3.8.40.0".
Disconnect the device, and "pnputil /delete-driver oemXY.inf" with the INF file you located in the previous step.
Connect the device again, and it should work, at least, it does for me. The problem is probably that the non-working driver is the newest (September 2021 vs. July for the ones from the download page) and so Windows prefers it over them.
Windows 11 update loaded Prolific PL2303 driver 3.8.40.0 and when I go to device manager it says "Please install corresponding PL2303 driver to support Windows 11 and further OS" This driver does not even attempt to communicate with my X10 CM11 hooked to my serial port. I had to go to Prolific website and load their current driver 3.6.81.357. (uninstall driver first) Serial to X10 device now working fine. Don't install Windows update for Prolific or it will change it back.
The ICUSB2321284 1S1P USB to Serial/Parallel Adapter Cable enables you to connect DB9 RS232 serial devices and IEEE 1284 parallel devices to your PC or Linux laptop or desktop computer, through a single USB port, as though the computer offered onboard connectors.
An innovative solution, the adapter cable features both a parallel and serial port that can be used simultaneously, delivering serial and parallel data rates of up to 921.6 Kbps and 1Mbps (respectively) to ensure optimum performance from your connected devices.
Note: When you restart your computer after you install your drivers, driver signature enforcement will be enabled again. This does not prevent your newly installed drivers from working, but does prevent any other unsigned drivers from being installed until driver signature enforcement is disabled.

When you troubleshoot issues with a serial or parallel hybrid device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
