Thank you - yes, that is clear and actually what I feared you might mean.
First, I am not an expert on the matter, so of course I may be wrong.
What I have been given to understand by a cabling pro that I have always 
found to be very reliable and sound, is that one cannot splice cat5 cable.
    At the very least it will no longer perform at cat5 levels.
    At the worst it will not perform at all.
In the old cat3 days (telephony), we used to use factory pressed M/F/F 
splitters and F/F connectors to do the sort of thing you described, but 
I have never seen anything similar for cat5.
Sorry - as I said, I could be wrong.

I shan't pretend I clearly understand the topology, but would it be 
possible to introduce a hub into the mix (something small)?  Would that 
help?

In case it helps ... in our house, the cable comes in through the 
vendor's connection (use to be a cable modem, but now it is an RJ45 wall 
jack from Verizon's FiOS), and into a router/firewall/switch.  From 
there we cable separately to each computer and printer that we need.  
The router/firewall/switch takes a public DHCP IP from the vendor (ISP), 
and it serves up private DHCP IPs internally (192.168.1.x).  The 
printers are configured with static IP's in the middle of the private IP 
range, as the router/firewall/switch (depending on make model and 
configuration) will normally serve up IPs from one end or the other of 
the range, an we certainly don't have enough devices to reach the middle 
- thus we avoid IP conflicts.
