Can I fax using an ethernet printer connection?

Faxing is done through voice lines, not DSL. If your fax machine is connected to the voice line as before, it should work as it did before. If it supports faxing with Macs, it still should; if it did not, it still will not. If you have gotten rid of your voice service, then you cannot use it. You would have to subscribe to an internet fax service instead.

My HP 6949dt

Are sure that't the model number? I can't find any references to it on HP site.

Looking at the manual for the 6940 it looks like it's describing how you can use the printer to scan a document and then send it as fax from the computer.

Also, while the printer appears to have ethernet and USB connections, it doesn't have a connection for a telephone line which would be necessary if it were able to send a fax.

Many previous Macs (my old G5 for example) had fax modems built in so that any document you could print you could also fax.

Among the ports on the back of the computer was a standard phone jack for connecting a standard phone line.

Newer Macs such as our iMacs do not have fax modems.

If your router has a back-up phone modem built in, it might be possible to use it as a fax modem. You could try adding it in the Print & Fax control pane. Just add a printer, select Fax, and see if the modem shows up. If it does not, you may need further instruction from your DSL provider.
