Adapters for card slots that we found to work after testing were available from. One way of checking this is that the correct type of adapter card requires a driver provided by the manufacturer whereas the wrong type does not and installs using a generic Windows driver. Update drivers with the largest database available. A card which just provides USB printing support only will not work. Get the latest official Prolific USB-to-Serial Comm port (COM/LPT/Serial) drivers for Windows 11, 10, 8.1, 8, 7, Vista, XP PCs. So, currently our parallel port products only work with plug-in PCI or PCI-Express cards in desktop PCs, and Cardbus or Expresscard adapters in laptops, as long as they provide an LPT port in the devices list.

We used to manufacture our own USB to parallel adapter for our products that had a parallel interface, but because an essential component for the adapter was made obsolete, and we couldn't get it from any other source, we stopped manufacturing these some time ago. If you choose to use it on another machine running 32-bit windows (or re-install the 32-bit version of Windows 10) then you need to be aware that, standard parallel to USB adapters don't work with our parallel products either. So, if your version of Windows 10 is 64-bit then you won't be able to use it on that machine, with that version of the operating system.


Unfortunately, the parallel version of our DrDaq data logger is not compatible with 64-bit operating systems.
