to :
xxx yyy ZZZ /test/prod/aasdasd.log1
xxx yyy ZZZ /test/prod/aasdasd.log2

and I want to sed only the fourth column

sed 's/devl/prod/g' awk '{print $4}' text
why must it be a sed one liner? anyway for your problem, its easier to work with fields
Code:
awk '$4 ~ /dev/{gsub("devl","prod",$4}1' file

use the more suitable tool for the job

       hp-makeuri - Device URI Creation Utility

DESCRIPTION

       Creates device URIs for local and network connected printers for use with CUPS.

SYNOPSIS

       hp-makeuri [OPTIONS] [SERIAL NO.|USB ID|IP|DEVNODE]

SERIAL NO.|USB ID|IP|DEVNODE
       USB IDs (usb only):
	      "xxx:yyy"  where	xxx  is  the  USB  bus	ID and yyy is the USB device ID. The ':' and all leading zeroes must be present.  (Use the
	      'lsusb' command to obtain this information. See Note 1.)

       IPs (network only):
	      IPv4 address "a.b.c.d" or "hostname"

       DEVNODE (parallel only):
	      "/dev/parportX", X=0,1,2,...

       SERIAL NO. (usb and parallel only):
	      "serial no."

OPTIONS

       To specify the port on a multi-port JetDirect:
	      -p<port> or --port=<port> (Valid values are 1*, 2, and 3. *default)

       Show the CUPS URI only (quiet mode):
	      -c or --cups

       Show the SANE URI only (quiet mode):
	      -s or --sane

       Show the HP Fax URI only (quiet mode):
	      -f or --fax

       Set the logging level:
	      -l<level> or --logging=<level> <level>: none, info*, error, warn, debug (*default)

       Run in debug mode:
	      -g (same as option: -ldebug)

       This help information:
	      -h or --help

EXAMPLES

       USB:   $ hp-makeuri 001:002

       Network:
	      $ hp-makeuri 66.35.250.209

       Parallel:
	      $ hp-makeuri /dev/parport0

       USB or parallel (using serial number):
	      $ hp-makeuri US123456789

NOTES

       1. Example using 'lsusb' to obtain USB bus ID and USB device ID (example only, the values you obtain will differ) :

	  $ lsusb

	  Bus 003 Device 011: ID 03f0:c202 Hewlett-Packard

	  $ hp-makeuri 003:011

	  (Note: You may have to run 'lsusb' from /sbin or another location. Use '$ locate lsusb' to determine this.)
