After som new tests I believe your assumption is right. Data from "copy" 
etc probably always goes into the first step in the spoolers handling of 
the data. See further below for more.

I think we agree more and more (or at least are more and more clear). I 
do not know if this is a good advice or not, I seldom buy a printer. In 
many environments it is of course like "choose your parents", but I am 
sure you know that  ;-)

Is this different from "net use" in some respect? I have used that in 
the command file below. The command file does two things:

 1) copy file.txt \\host\queue
 2) net use lpt1: \\host\queue
     copy file.txt lpt1:

I have done this for one printer using different queue names. The result 
is that it works for one name, but not for the other. I also used a 
third name, but I am not quite clear if this is a queue name. It appears 
however in the printer queue window header. (I did not have time to 
check this - perhaps I will do that later.) When it worked it worked in 
both case 1 and 2 above.

To make this more understandable I give the command file and the output 
results below.

I could check this more in details than I have. I do not know however if 
there is more to gain from that. Perhaps it is better that other people 
try to test this too. In my case I believe this means that I can print 
from Emacs simple black and white. I takes some time to test which queue 
to use, but the command file below could make that job easier of course. 
I however still suggest avoiding that job, printing through the web 
browser instead.

I also do not know if there is any reason to believe that one queue 
alwasy work on any printer (if there are several queues).

Here is the command file *print-copy-test.cmd*:

And here are the outputs of my tests using the command file above (I 
removed the output from the first net use /d):
