Actually it should be possible to use the WiFi link, BUT windows guest only sees the virtual wired link supplied by the Virtual Switch software. It knows nothing about the WiFi that eCS can use. WiFi is nothing more than a cable replacement between a NIC and something else (usually a wireless router). Think of it as a completely separate machine, running windows, and connected to the network by a cable, not WiFi. If that network has a router, that has wireless capability, then other wireless devices can be seen as part of the network that windows is connected to. The printer is part of that network, and is connected to the router by a WiFi link. Windows itself doesn't need to know anything about the WiFi link, all it needs to do is communicate with the router, and the router communicates with the printer. > If >that's possible it opens up other options to support currently >non-supported by eCS WiFi cards - i.e. VLAN into the virtualised windows >session and route out through the WiFi link to the outside world. No, that doesn't work. It *may* be possible to do that, if the virtual machine software could be made to expose the actual hardware to the guest software, but it currently doesn't do that. All that the guest sees is the virtual cabled NIC. At the other end of that "cable", the "physical" link to the router can be a WiFi link, but the guest knows nothing about that. >> As far as the >> guest XP system is concerned, it just sees the printer on the network, >> and has no idea that it is running in a virtual machine.

You may have better luck trying to get that part to work with a real windows machine first.

What I see with the i960, using the CUPS test print, is that all of the black parts seem to be correct. Part of that is a circle, that has segments that are supposed to be filled with various colors. The colors appear to be correct, but the circle that they make is about twice the width of the black circle that they should fit into. >> I can get the MP620 to work with CUPS too, but it >> puts a line of blank dots, between each line of dots, causing only the >> top half of the page to be printed on a whole page.

WiFi simply replaces the cable with a radio. It seems that you are doing better than what I was able to achieve with my brother's printers. I haven't had time to set up CUPS for my own printer yet. I have only been home for a couple of days, and I had to put a new power supply into my main machine to get it to come back to life (don't know how a power supply can go bad when it is turned off, but...). That, and catching up, have taken all of my spare time, so far. -- **************************** From the eComStation of Doug Bissett dougb007 at telus.net **************************** ...
