printing under command line

Long time no see! Today I am going to have a very exciting thing:
printing under command line in linux
Which is very useful if you need to do the work very fluently!
First install cups and its pdf converter by:

sudo apt-get install cups  cups-pdf

After this, you should have both lpstat and lp commands.
if your computer get right connected with printer(cups will install some printer drivers on your PC).
Now let us see what printers you can access to.

sudo lpstat  -p #show printer with their working status

[rugal@domba-06 mnt]> sudo lpstat  -p

sudo lpstat  -s #show printer with URI

no system default destination
device for cms: socket://130.179.25.7:9100
device for Coral: pacups-lpd://coral/
device for Diamond: pacups-lpd://diamond/
device for Emerald: pacups-lpd://emerald/
device for Fluorite: pacups-socket://fluorite/
device for Mail: mailto://cs.umanitoba.ca/application/pdf
device for Opal: pacups-lpd://opal/
device for Zircon: pacups-socket://zircon/

Take instance if you want to print something with Diamond printer, you need to:

lp -d Diamond filename

Also in lp you could specify a lot of printing options, for instance do two side printing if your printer supported:

lp -o sides=two-sided-long-edge -d Diamond filename

But the bad thing is, you could only print txt and pdf files, still a long way to go!
I cannot wait to use it! Have a try!
