Lexmark x4550 wireless scanning

    I have a Lemark x4550 wirelessly connected to my WindowsXP desktop
    computer. It prints fine however I can't get it to scan. Using the control
    panel on the printer it asks me to select the computer to which I want to
    scan, I choose the computer and it starts "Downloading Application List".
    This usually results in an error stating it "Cannot retrieve application
    list". However sometimes it will give me a list of applications and if I
    select one of these and try and scan an error screen comes up stating the
    scan failed. There's also no scan icon in the Lexmark Imaging Studio. Any
    suggestions.

    No help, I know, but I've never really heard anyone talk about being
    happy trying to scan wirelessly, except for some specialy usages like
    barcodes.

    I second MM, I have never heard of scanning wirelessly. There is too much
    communication between the computer and scanner for wireless to work.

    The Computer needs to talk with the scanner to set the parameters and the
    scanner needs to talk with the computer to send the image back. This must be
    done in real time.

    I think it has as much to do with the sheer volume of data that must be
    quickly passed as anything.
    Even "low rez" scanning, say actual size @ 72ppi generates a lot of
    bits, and of course if the scanner has to wait for data buffers to
    clear from scanner to puter and whatnot, it often just craps out, to use
    technical term.

    I think barcode scanning can work okay, like grocery store encoding and
    the like, but there isn't really very much data involved to read UPC
    stripes.

    There's no reason the protocol and network used cannot handle the
    bi-directional needs of scanning. Wireless "g" and "n" are sufficiently fast
    enough (if no other problems exist) to manage the data flow. There is
    nothing inherent to a wireless network that makes it less capable than a
    wired network given that the wireless network, softwate, protocol, layers,
    and hardware are configured correctly. Come to think of it, why would
    Lexmark release a line of wireless printer/scanners that won't work on
    wireless networks?
    If the scanner works fine with the laptop, it follows that the scanner is
    fully cappable of interacting with a computer over a wireless netwrok.
    Therefore, the problem must be with the Desktop or the configuration. I'm
    curious if you ever connected the laptop to the Lexmark using USB?

    Some networked printers have to be configured as a local printer to be
    successfully set up as a networked printer. Connect the Lexmark directly via
    USB, (re-)install drivers, (re)-install software. Can the Desktop
    communicate with the Lexmark without errors? If it can, shut everything
    down, disconnect the Lexmark from USB. Restart the Desktop, and Add the
    Lexmark as a network printer or change the Port for the printer that was
    installed - Check your manual for best method if one is suggested. Can the
    Desktop communicate with the Lexmark without errors now?

    What happens if you share the Lexmark on the laptop and then connect to the
    share (Add -> Network Printer)? Can the Desktop communicate properly with
    the Lexmark now?

    It all depends on how smart the scanner is, if the scanner is a true
    network scanner which can dump encode data and dump files to a NAS
    automatically, the bandwidth is pretty minimal -- Just look at the size
    of the resulting file.

    However, if you're talking a $35 bargain basement scanner, then you're
    absolutely correct about the bulk of data.
