Thank you very much for those pointers. Short reply is that it worked!
I had thought that I may have missed the simple solution when going
through all the GhostScript and foomatic-rip perl scripts to try and
find a limiting factor for an embedded system.
When the simple print test page from cups web page failed I then went
for the more complicated system. In fact leaving the HP990c as the
raw printer I would get PCL_Unsupported Personality errors and now I
gather (from the openlinux printing page) that the HP 1010 requires an
additional 8 bytes to be sent for that error not to occur. By setting
up my Windows machines with the correct HP LaserJet 1010 driver and
pointing to the http://[NSLU2IP]:631/printers/hp990c link they
actually sent the correct commands and printing started almost
I wasted a few days trying to see why foomatic could be failing but as
you said the lack of memory and possibly other dependencies meant that
it was never likely to work.
Additionaly I have found that I have not had to re-enable the swap
space to get the printing to work even with pages with large amounts
of graphics, however I may yet find that large multiple documents and
queues will cause problems but none as of yet.
