2 broadband connections, 2 routers, 1 switch

I've been trying to figure out a problem at work.
We have two broadband connections (1 DSL and 1 cable [roadrunner]), as we need redundancy if one provider goes down.
We have one big printer that everyone hard wired can print to, as the dsl modem links to this thru it's router.
Some of the laptops (not all for some reason that I cant figure out) can print to the printer when wired into the network and even wirelessly.
However, a couple of the laptops cant print wirelessly, and here's where I cant figure it out.
(by the way, the laptops are macs...).
There's two networks running in the office, because of the two net connections, and this is part of the problem.
Is there any way of connecting both routers (and thereby both net connections) to our switch?
Any ideas?
Thanks!

Get a dual WAN router and move everything else on to switches.

get yourself a dual WAN port UTM, a wireless AP, and be done with it.
JFTR, they're gonna run you about 500 bucks and up.

Easiest way is the Dual WAN Router.
NewEgg has one for $150, and includes VPN support..

The old school method:
Setup a PC with three network cards, it will act as your DHCP Server.
1 network card for...
the DSL
the Cable
& the Switch
Bind the DSL and Cable connections on the PC, and Connect all the devices to the switch (Including the AP), have them point to the PC as the DHCP server.
There are several apps out there to turn your PC into a router. Many of them are free and have binding support built in.

would still need an AP attached. And with the printer attached, it would leave you with only two available wired ports.

this does work, but it adds more maintenance and downtime.

Yeah i know - Thats why i prefaced it with "The easiest way is..."
And there are many affordable 24port switches out there - thats the easy part of that setup is the switch.
I was just offering an alternative, after all it is the old-school way of doing it.

1 dual wan router as suggested above
1 16 or 24 port switch
1 WAP ( reuse a wireless router if you have one configured as switch/WAP)
Disable dhcp on the dsl modem and set it for passthru and let the dual wan router handle all of the NAT translation and dhcp duties

true enough. but remember: the less points a network has, the less likely a failure will occur and take down the entire infrastructure.
