Everything here is gigabit (NICs, router and switch) except for two ethernet 10/100 network printers. Will attaching them to my switch slow the whole network down?

Of course not. Why would it? Switch negotiate the speed with the device connected and if errors occur you can change the speed manually on the switch. – mnmnc Mar 30 '13 at 23:18
why would it? I read that "All devices on a network will auto-negotiate to a common sped to a void incompatibility bottleneck" and "IMHO unless you ar planning to pjase out all of the 10/100 mgabit nics on you network don't bother going to gigabit" and also ". One reader said that merely plugging a NIC running at 100 Mbps into a gigabit switch was enough to force all gigabit links to 100 Mbps speed" – Max Hodges Mar 31 '13 at 12:59

You should not have an issue. Point to point should switch to what the device supports. If you were on a token ring it would matter. Through a modern router or switch there should be no issue. Make sure your switch does not have some sort of force mode enabled too.

is "force mode" like this "flow control" issue? – Max Hodges Mar 31 '13 at 13:01
