I took Gerry's suggestion and wrote a small example and tested it. My setup
will be a little different from yours so yours may have better results.
This is my setup:
Workstation sharing a USB printer on domain1
W2K Adv. Server running IIS on domain2
I mapped lpt1 on the server to the printer share on the workstation
I made a virtual directory [bob] on one of the server's partitions and put
my .asp file in it.
Rights: Administrators (Full), IUSR_FS1 (RX).
I created a data directory [bobdata].
Rights: Administrators(Full), IUSR_FS1 (R)
I call the .asp file which is written to copy ticket1 to lpt1, which
hopefully will send it to the printer.
My results are:
1. When calling the .asp file from the workstation, I get prompted for
credentials [anonymous users are disabled] and even though I give it admin
credentials, I get permission denied.
2. When calling the .asp file from the server [same way]
http://fs1/bob/printit.asp, it works. The line number that returns for
Permission Denied is line 22, the copy line.
Here is my code:
<%@ Language=VBScript %>
<%
Option Explicit
Response.Buffer = True
Const strPath = "d:\bobdata\"
sub goPrint(strFile)
dim fso, strPort
set fso = CreateObject("Scripting.FileSystemObject")
strPort = "lpt1"
Response.Write "Printing " & ucase(strFile) & "..."
fso.CopyFile strPath & strFile, strPort
set fso = nothing
Response.Write "complete!"
end sub
goPrint "ticket1"
%>

My web server is not part of my other domain so I cannot test a system in
that domain without config changes to one of my workstations. Perhaps you
will have better results. If that doesn't work, I have one other
possibility.
