My computer has two network interfaces, eth0 (wired) and wlan0 (wireless), to connect to my router. The wired connection goes via a small network switch to which a laser printer is also connected.

The computer normally uses the wired connection but sometimes I need to disconnect that and use the wireless so that I have a wireless connection to the router but the cable is disconnected from the router leaving my computer connected to the switch which also has a laser printer connected to it.

Is there any way that I can use the laser printer via eth0 when my computer is running on wireless? -- Barry Samuels

So long as eth0 is up and running (you can check with ifconfig), since (according to your description) there is a cable connection computer --> switch --> printer via eth0, you should be able to print directly to the printer using its IP address.

You may need to use "route add -host pr.in.te.r eth0" to ensure that the computer uses eth0 for the printer, where "pr.in.te.r" is the IP address of the printer.

I hope this advice is sound! Ted.

Thanks Ted, that route incantation worked. They didn't tell me that one when I was at Hogwarts.

Very much obliged.

Glaqd it worked, Barry. While I'm at it -- I enjoy your "beenthere-donethat" website. Lovely photos.

However, I take issue with you on one point. On the Cambridgeshire page, you write of Ely Cathedral: "Ely Cathedral is known as the Ship of The Fens because, being built on a low hill, it stands above the surrounding land like a ship on a wave."

Low hill? Excuse me ... In the Fens we measure height in microEverests (uEv for short), so 1 uEv is slightly less than a centimetre. In terms of the impact of height in the Fens, 1 uEv makes about the same impression as 1 ft alsewhere in Britain.

The summit that Ely Cathedral stands on is about 20m above sea level, i.e. 2000 uEv., which makes it comparable with one of the Grahams (Scottish hills between 2000 ft and 2500 ft in height, compared with the Corbetts (2500 to 3000 ft) and the Munros (3000 ft and up)). So the Ely Cathedral summit is equivalent to a 2000-ft Scottish hill.

Compare that with Pidley, which at 35m stands on the highest point in the Fens. This is 3,500 uEv, so equivalent to a Scottish 3,500 mountain. Pidley also has its own dedicated Mountain Rescue Team:

So, Barry, very nice website, but please get things in proportion!

Best wishes, Ted.
