EPSON Stylus CX7450 with FreeBSD
--------------------------------
UPDATE (22 OCT 2008): The top of documents get cut off when printing.
  I can't seem to find a way around this.  If someone figures it out,
  please let me know.

>> Ensure this is in your kernel config (you might need others, these are the basics ):
	device   ohci
	device   uhci
	device   ehci
	device   usb
	device   ulpt
	device   uscanner

>> Install the following software:
	- print/cups
	- print/gutenprint and print/gutenprint-cups
	- graphics/sane-backends and graphics/sane-frontends
	- graphics/xsane

>> Add this to /etc/rc.conf:
	cupsd_enable="YES"
	uscanner_load="YES"

>> Notes and hints:

Configuring CUPS:
	You can configure CUPS several ways. An easy "UI" way is with a web browser.
	Open localhost:631 in a web browser.  You'll probably have to use a CX7400 driver for the 7450.

	Standard lp* commands are in /usr/bin/
	CUPS' lp* commands are in /usr/local/bin

	# chmod -x /usr/bin/lp*
	That'll make the base lp* commands non-executable, defaulting to CUPS'

	Or, ensure that /usr/local/bin is in your $PATH before /usr/bin

	Put this in /dev/devfs.conf for users to access the printer:
		own ulpt0 root:cups
		perm ulpt0 0660

Scanner:
	For the scanner, cp /usr/local/etc/sane.d/dist/epson.conf to /usr/local/etc/sane.d/
	Make sure the following is in epson.conf (comment out SCSI and parallel stuff):
		usb 0x04b8 0x0838
		usb /dev/uscanner0

	Use the command "sane-find-scanner -q" to get the information.
	Use "scanimage -L" to make sure the scanner is available. If it's available as root, but not a user,
	you'll have to set permissions for the devices:
		- Add the user to the "operator" group
		- Put something like this in /dev/devfs.conf: perm uscanner0 0660

	If you installed "xsane", you'll probably want the GIMP plug-in. The xsane package doesn't seem to do this by default,
	so you'll want to compile it from ports. (WITH_GIMP).  Then, you'll have to enable the plug-in for GIMP:
		ln -sf /usr/local/bin/xsane ~/.gimp-x.x/plug-ins/xsane

		The plug-in will be available from the "File -> Acquire" menu.
