  1. If the 7500 is connected via it's 10/100 Ethernet port and it goes to sleep, will a print operation directed at the 7500's USB attached printer awaken the 7500?

This may not be relevant, because it's not USB, but a network print operation directed at an Apple laser printer attached to my Mac and shared via LaserWriter Bridge software would not wake up my machine. I moved the printer to a 7200 "server" and turned file sharing on; that prevents sleep and guarantees printer availability. I like this solution because I have Energy Saver turn the 7200 on each morning and off each night, and it's kinda nice having a small file server for quick work-in-progress backups.

I don't have an answer, but 2 comments:

My 8500 on a home ethernet does not wake its monitor when I move files to/from it from another computer. Now I question whether it's still asleep, or just not waking the monitor.

My 8500 has a Keyspan USB card (OS8.1) and when it goes into deep sleep, the USB dies. I have to reboot to get the USB back. This is NOT when I use the sleep command, but some time afterwards.

YMMV. Will be interested to see your results.

I found that I was spoiled by the Appletalk network of providing services to all the machines on the network without any one of them having to be dedicated to "serving up" a printer. Alas, with USB printers, it appears I am forced to dedicate a machine.

In that vein, I have a 7500 enroute to dedicate to the task. Two questions:

  1. If the 7500 is connected via it's 10/100 Ethernet port and it goes to sleep, will a print operation directed at the 7500's USB attached printer awaken the 7500?

  2. Will the USB printer sharing software (It's a Canon S800) prevent the 7500 from sleeping? My experiments with a Powerbook had that Canon software hitting the hard drive every minute or so. YUK).

Received this info via e-mail: "The Powerbook G3 (FireWire) was the first Apple machine with wake-on-lan capability. I beleive all the machines made after 2000 have that ability, but not the 7500."

Managed to do some experiments that are consistent with this: Using a Pismo, I successfully woke up the machine from a remote iMac issuing a Print operation. However, the delay or lack of proper handshake resulted in the iMac reporting that the print failed.
Re-issuing the print worked fine so the Pismo manages to wake on LAN and not lose the USB. Of course if the Pismo isn't sleeping, everything goes without a hitch.

FYI

You can prevent it from going to sleep by setting the sleep control in the Energy Saver control panel to Never.

If you want the display to go dark without putting the computer to sleep, you can set the display to go dark separately in the Energy Saver control panel. To get the separate display control, click on the button Show Details on the Energy Saver control panel.
