If this kit is desigend for your printer then it is a better way to go. Other wise you would have to go with wireless printserver. The problem with most printservers is if you can find one that is compatable with your printer it will most of the time only offer just the print function. So if you have a mulitfunction printer you would not be able to use anthing else but the print part. Now I would definatly look at if this kit will give you full fuctionality wirelessly from your printer.

As an update more and more printers are coming with built in wireless for just that reason. 

Thanks for the advice. I had hoped to avoid anything protruding but if thats the only way to get maximum functionality I guess its worth it :-) John
