If you want to do any sort of printer sharing you will need to be on the same network.  Are you currently connected through a cable with the Dimension and wirelessly with the XPS to the same network?  If so you could simply "share" the printer from the Dimension and from the XPS print to the printer through the Dimension.  You would just have to keep your dimension on all the time. 

 

That is assuming that there are Vista drivers for your printer in the first place which I'm not sure of.  You will not be able to use any of the other features of your all in one, just printing in case you need to be able to scan or fax from the XPS.  In that case you will most likely need to look into a networkable all in one printer.

 

 

 

Easiest way is to add a wireless print server.  Get one with wired ports as well for your non-wireless computer and it should work ok.  Other option is a regular print server with both computers attached to the same network.  (One wired, the other wireless)

Thanks. I will check out the cost on that and see if it's worth it. 

 

I'm looking at the wireless Dell Model and it also accepts a USB input. I assume I can use both. The USB for the old Dell and the wireless Card for the XPS One

Yes, both PC's are using the same network. My preference is to not leave the Dimensions running all the time but that looks like a possible option. I was hoping that if I went with a 'wireless' printer that the printer would accept both PC's. One wired and one not. From a cost standpoint, I would rather get a new printer and pay $150.00 for it rather than keep the 3 year old model I paid $100.00 for and avoid spending $70.00 for an adapter.

 

Thanks
