    As far as I know, nobody has succeeded connecting parallel lcd's using this type of cable. It looks like these cables use some especific driver, and this driver has been developed to handle only printer signals.
    Please, keep us updated about it.

    You can't use those USB>Parallel converters it simply won't work.
    Alternatives:
    - LPT PCI card (cheapest option)
    - USB backpack for character LCD's, they exists but software support might be limited.

    If you don't mind getting quite technical, go to :here: where you will find an experimental USB to Parallel port driven (graphical) LCD screen interface.

    Well USB LCD's (VFD's too :p ) both character and graphic are already available. Main issue is; they need support from the major LCD apps, as most of them are proprietary designs.
    Henri's USB LCD is currently the most interesting as it's supported bij LCDinfo and LCDStudio v2.

    well i obtained a LPT card today, installed etc. etc.

    but yet im not getting any readinsgs out of the display.
    ive read a guide on another forum to no prevail, which involes port95 and, LCDcenter.
    but im not getting anything bar the top row of the display black and the bottom row empty :<
    ive checked my wiring 10 x over and theres no dry solder, and no bad connections.

    any ideas lcd gurus out there =D

    Check the LPT I/O port address in Device Manager and put that in the LCD apps config. Try Smartie too.

    Huren,
    I'm no LCD guru, but a few tips for trouble shooting:
    1. Do you have (or have access to) a parallel port printer ? If yes, then use it to see if the card is ok in the first place.
    2. Did you install port95 if you are using Win xP.
    3. Set the LPT BIOS mode to EPP.

    Hope this helps and good luck.

    The fact that the LCD works on another PC but not on another would mean that it is not a wiring problem, but a setting issue (or a dead/faulty PCI card).
    To set LPT mode to EPP is done by entering the BIOS, but I'm not sure how you would do it as your mobo does not have any LPT ports. Maybe have a look at Device Manager ?
