# USAGE:
#	Copy this file (visionfs) into the /usr/spool/lp/model directory
#	Run mkdev lp
#	
#	Printer ---> Add Local
#	Name: The name of the printer
#	Description:  Printer Description
#	Model: visionfs 
#         mkdev lp will overlay this file in /usr/spool/.../interfaces directory
#	Device: /dev/null
#
# 	vi the printer's_name file in the interfaces directory
#		/usr/spool/lp/admins/lp/interfaces
#	Change the line PRINTERPATH under Global Variables Section below
#		to read	PRINTERPATH=//PC_IP_OR_NAME/PRINTER_SHARE_NAME 
#		Where PC_IP is the IP Address of the PC
#			Or use the PC name in /etc/hosts
#		PRINTER_SHARE_NAME is the name of the shared printer on the PC	
#
#		For example if the PC is called pc1 and the printer shared on
#		pc1 is called HP1100A then the PRINTERPATH variable unde the 
#		Global Variables would look like:
#			PRINTERPATH=//pc1/HP1100A
#
#Global Variables
# printerpath = //pc_ip_or_name/printer_share_name ** Change for each printer **
PRINTERPATH=//PC_IP_OR_NAME/PRINTER_SHARE_NAME
