[Eclug] OT: any printing to NTA thin clients?

Sorry for the OT post.  But most subscribers work in the industry and 
some MIGHT have some knowledge of sources of information.

I've just inherited the support and further app development for a bunch 
of thin clients running web based apps on NTA 6010 thin clients.  These 
seem to run some flavor of *nix as their proprietary OS.

My questions relate to printing to these boxes:

It appears that they may use cups as their print server software (as I 
can access it local with localhost:631 and actually get connected.  But, 
trying to do anything requires the admin username and password.   As no 
one has ever (so they say) set this up and I do not have any real admin 
access (because its a closed OS) what can one use for these values?

If anyone is familiar with this line -OR- if anyone knows of any source 
of info (other than their source - devonit.com) please advise.  And, of 
course, if anyone has any actual usable knowledge of these devices 
please share it?

Thanks for reading and thanks for responding.
