Or you forget to install the printer drivers.
I was not happy to find Winfixer noted when I used google about the error message, your lexmark and XP.
Just to be sure, scan the machine with EWIDO and HOUSECALL. If you find Winfixer, here's a noted tool.
I have moved my lexmark x1100 all in one to another pc I am now getting the message 'the handle is invalid ' what does this mean and how do I fix it? Thanks
