Let us go back to the beginning before we progress. I assume a lot so correct me where I am wrong.
1) First you connected usb lead to router and installed the drivers under windows to your windows computer
In windows you found some kind of setting to PUBLISH your printer to allow SHARING with other users
2) You booted up Lubuntu and opened the cups page and under discovered network printers you saw your printer name?
3) You then gave it the correct subnet addrress as 192.168.1.1:9100?
which under lubuntu was showing as socket://192.168.1.1:9100
and then you installed the linux driver for your printer
OR did you have samba running on lubuntu and under cups page saw a samba listing and connected thru samba?

TC had a similar question and our friend Juanito replied and the Orginal Poster did not say it was wrong
http://forum.tinycorelinux.net/index.php?topic=345.0Juanito mentions ipp and that is related to avahi network discovery tool.
Now I pinch an image off the net to talk about ipp and lpd
when you redo cups look at the image after you have also started avahi......I want you to tell us if you can see
"internet printing protocol" or "ipp" as an option AND
"LPD/LPR" host
IPP seen then
########
then click the radio button next to ipp and press continue and then see if you can see your printer.
IPP not see but LPD seen
##############
then click on that radio button and press continue
according to a google search, you may need to input lpd://192.168.1.1/L1

Just to repeat
if the ethernet cable is connected to a windows computer, it controls your printer and you need to allow sharing of that printer from within windows
In linux on the cups page, you have to allow cups to see shared printers etc as per image
You need to have avahi running to discover the wireless router
and then in cups you are likely to click on ipp and follow steps for that
(I don't have a router capable of connecting an usb printer)
good luck
(B) As I have a desk tower computer with no wireless I hope Juanito may help you with your wireless stuff. CUPS is supposed to have its own ipp backend but if you can't see any ipp as per above image then maybe you may need to have wireless_tools installed and running and try
sudo iwconfig
to see some networks, I don't know, its all mumbo jumbo to me
