install a printer from the command line

[David Vincent]

hi list.

is there a command-line method to installing a printer?  i've got a 
machine here which is running out of memory loading the printer database 
  after installing the foomatic-db-gutenprint package to get the needed 
driver.

i'm running xubuntu 7.04 with 140mb RAM so this is using the 
system-config-printer applet, and the printer i am trying to install is 
a (horrible all-in-one p.o.s) epson stylus cx7800.

all i want is to share the printer capabilities over my wireless network 
so if someone knows an easier route to making these new multifunction 
epson stylus things work with ubuntu i'm all ears.

thanks.
