The first. Cut and paste:

You can select Duplex/Simplex, A3/A4, manual feed, paper tray source
and output trays using the -Coptions option. (For the printers that
support those options of course). 

Available "-C" options:

duplex 
      Enable duplex printing (print on both sides of the paper). 
tumble 
      Tumble the duplex printed papers. 
tray=number 
      Select paper source (source 0 (zero) is normally the highest
      input tray, but this might vary between printers). 
paper=type 
      An alternativ way to select input tray, using paper size/type.
      Valid types include: a4, a3, paper, transparency, oh 
manual 
      Select manual paper feed. The printer will display a message
      on it's display and wait for you to insert a paper in the manual
      feed slot and press the "Continue" button.

This is not documented in Sun's manual pages... they're pretty
much the same as NetBSDs. Hmm... maybe this is added by our local
sysadmin.

Uh, well, that's hard. I'm sharing the printers with 300 other users
and the closest one is in a parallel univ.. corridor.

Thanks anyway,
