Subject: Duplex printing available
 
 The laser printer in the Computer Lab 2105 NW now has the ability to print
 double-sided (duplex).
 
 From the chemistry Unix server, use the following command to print a file
 with the name "filename" double-sided:
 
   lp -o duplex filename
 
 From any other assimilated Unix machine in the department, using a default
 print queue other than 2105nw, use the following command:
 
   lp -d 2105nw -o duplex filename
 
 Meaning of the options:
 
      -d destination queue, if different from default 
      -o print option
 
 We have also created a print queue that prints duplex by default; the
 following print command will work from any assimilated Unix machine:
 
   lp -d 2105nw-duplex filename
 
 
 To print double-sided from PCs and Macs, select the "Double Sided" print
 option in the appropriate print dialog box.
