Come on. That is very selective reading of the questions here.
Nearly every answer that I put here about Lexmark is because a customer has LOST their CD.  Is that Lexmarks's fault? 
Why so many, because Lexmark are a VERY successful company at marketing their products to consumers. 
However if one has lost a CD containing drivers for W98 or similar OS, then you've had it as Lexmark withdrew support for those OSes shortly after Microsoft did.
