Type the following command:

	l /dev/lp*

you should get a line (or more than one line) looking something like:

c-w--w--w-   2 bin      bin        6,  0 Sep 21  1990 /dev/lp

The important number is: --->---> ^^^
This is the Major Device Number.

If you don't have any printer devices left then type:

	grep lp0 /etc/perms/*

and you should get the following line:

/etc/perms/inst:RTS	c222	bin/bin		1	./dev/lp0	6/0

The Major Device Number is:	--------->--------->-------->---->---> ^^

	
To recreate your printer ports type the following, replacing the question 
mark with the Major Device Number from above. 

mknod  /dev/lp 	c  ?  0
mknod  /dev/lp1 c  ?  1
mknod  /dev/lp2 c  ?  2

ln /dev/lp /dev/lp0



Good Luck.
