That's something at least. Some progress! But I wonder why your PS file
is 3M (20%) larger than mine?

Thank you. It doesn't look any different from mine.

So, an image is produced, but mostly in black and white as before? I was
also wanting to know the result of brian.ps being printed. Please would
you do that?

  lp -d LaserJet_M452dn_HPLIP -o raw brian.ps

Using 'o raw' means that the cups-filters system is avoided and the only
filter being used is hp, which transports the data to the printer. We
can avoid hp too with

  nc <printer_IP_or_host_name> <port> < adrian.ps
  nc <printer_IP_or_host_name> <port> < brian.ps

nc is netcat. <port> can be 9100, 9101, 9102 etc for a socket connection
(JetDirect), 631 for the IPP protocol and 515 with the LPD protocol.

This is likely to be the final bit of testing. :) All that is needed is
the results from your three tests.

Thanks in advance,

Brian.
