ttmcmurray,
First, thanks for the help (also davevt31). I am somewhat clueless.

Second, per davevt31, I uninstalled the Epson from the main pc (DELL) using programs/features. I reinstalled it (hard, had to do so from the Epson website to get a Vista version). There was no difference. Could still see the printer from the Toshiba, but not connect and print to it.
Third, how do I delete the printer from the toshiba witout using add/remove programs? I guess from programs, click on Epson folder and click on uninstall (I am running between computers). Or am I deleting the printer from the printers section in control panel and not/not deleting the epson program. Maybe you mean the later. I don't have the epson on the Compaq because I just restored the XP OS from the D drive and haven't reloaded it yet. the compaq is a desktop and is hardwired to an old HP all in one so I haven't focused on it much--except for it inability to hold an internet connection (hence the purchase of the new router after first redoing the OS).
As for more specifics, I have vista on the main pc (dell 32 bit) and the toshiba (64 bit), the compaq is XP, at least SP2. If I am on my main PC and click on network and sharing (via the systray) and then go to my Network Map I get: Main-PC and CherylJohnst-PC, which both go to the Johnston Network and then to the Internet. the Compaq does not show up, I guess because it is XP?? But I get to the internet on the Compaq just the same (have not been able to see if it still has trouble holding connections b/c I haven't got past the printer issue on the Toshiba--which we need to print from). Also, in network and sharing center, everything is "on" except password protected sharing.
Under Computers and devices (still from Main-PC) I have Cheryljohnst-PC Media player, Main-PC media player, Intel Media Server (Main-PC), Cheryljohnst-PC, Compaq, and Main-PC. If I click on Cheryljohnst-PC I get shared and printers. If I click on Main-PC I get Epson Stylus CX3800 Series, Microsoft Office Document Image writer, Public, and Printers. If I click on printers, I get Epson Stylus CX3800 Series, Microsoft Office Document Image writer. There are no printers under CherylJohnst-PC Printers (which seems reasonable).
In my control panel, printers, the Epson Stylus CX3800 Series is the default. The Epson Stylus CX3800 Series (Copy 1) also is listed (I don't know why I get multiple copies).There is also a Microsoft Office Document Image writer and Microsoft XPS Document--I don't really know what they are.
I guess I "log into" my DIR 655 by going to the internet http://192.168.0.01?? I did that and DHCP Server is enabled. I don't know if the hardware and IP addresses are sensitive, so I did not show them below. The IP addresses are always what I see when I look at each computer--the IP number has not changed. I see below that something expires in x hours and minutes. I guess you are saying I should click on "reserve" for each client?? I will wait to do that or otherwise proceed further until I get your response, hopefully I will hear from you again.
