So are you saying:

Internet -> FIOS router -> Linksys 192.168.2.x -> Linksys 192.168.1.x

(Where the -> side of each device is the WAN port.)

Your wording is a little vague, but the above would be the expected 
arrangement if you wanted to keep the Linux boxes most protected.

Have you also adjusted the firewall rules on the 192.168.1.x router to 
permit inbound SMB traffic from the 192.168.2.x network?

I'm confused. The above suggests the client is in the 192.168.1.x 
network, but you said you were trying to print from a Windows box which 
you previously said were all in the 192.168.2.x network. Is 
192.168.1.153 the address of the 192.168.1.x router?

In any case, one problem you might need to deal with is name resolution. 
You mentioned previously that the Samba print server had a static IP 
address, which may make this irrelevant, but normally Samba uses 
Microsoft's NetBIOS protocol for name resolution which depends on 
broadcast packets which won't normally traverse your routers. Accessing 
the printer via IP or adding an entry to the HOSTS file on the Windows 
box might be necessary.

Another option to consider is to proxy the printing through CUPS. I've 
actually found it to be a useful tool in doing this kind of router- 
traversing printing, as I think it offers better diagnostics than Samba.
