                Wireless (WL) Printing
                #############
                I recommend you set up your router to reserve an IP for your WL printer first.
                Be aware that some printers advertised as wireless printers may not have
                full hardware.     WL ink levels can be checked by using your web browser 
                eg url= 192.168.1.7  -- once the printer IP is set.

                Epson ink levels, once printer is set up
                ############    prev tested on TX100 
                $ tce-load -wi readline

                Extra printer calibration
                ###################
                $ sudo cups-calibrate
                (and enter only numbers as directed after viewing the test page)

                How to use  after reading above
                ########### 
                $ tce-load -i gutenprint 
                $ sudo /usr/local/etc/init.d/cups start
                $ sudo passwd # to set up a root passwd, if not already set 
                       as /usr/local/etc/cups is root owned
                Next, open your web browser to  http://localhost:631/admin

                Do NOT click on "Find New Printer", instead click on Add Printer
                Then make your selection. Remember to click the "Add Printer" button
                to then get options to change paper size etc. At the end of that process
                a popup (ensure you allow popups in browser settings) will 
                ask for user, input root and your new password please. I did not need
                locale set.

                After setup (recommended) pulldown administration and make your printer
                the server default.

                During first setup, sharing will fail. YMMV. We fix then after defaults setup
                go back to http://localhost:631/admin
                Tick the box for sharing and any other changes you wish
                -> cups server will restart. Then click on printers button
                click on the printer you just set up
                status (ideally should show) Idle, Accepting Jobs, Shared, Server Default

                Then test printer. 

                If printer not found read cups-filters info please.

                For my Canon and my Epson I did not need to run next command
                Only run it if you can not find your printer PPD or maybe if you are runnng avahi.
                $ sudo generate-ppd.sh

                For persistence 
                ################
                (1) Add these lines to /opt/.filetool.lst 
                etc/shadow
                usr/local/etc/cups/cupsd.conf
                usr/local/etc/cups/printers.conf

                (2) You can choose to add gutenprint.tcz to your 
                boot.lst depending on how frequent you think you might do printing.
                You can also command to start cups by
                $ sudo echo '/usr/local/etc/init.d/cups start' >>  /opt/bootlocal.sh
 
                On reboot
                ##########
                Assuming you have done the persistence suggestions, load gutenprint 
                and then start cups with
                $ sudo /usr/local/etc/init.d/cups start
                and if you are using a WL printer and need avahi
                $ sudo /usr/local/etc/init.d/avahi start

                #######################
                NO MATCHING MODEL FOUND
                ######################
                If you are not sure which PPD is best for you, uncompressed PPDs are
                created at /usr/local/share/cups/model/gutenprint/5.3
                after running $ sudo generate-ppd.sh 

                Before rebooting and losing all of them except your persistent ones,
                you may like to copy some into your home dir. CUPS allows you to try 
                a PPD from a non-system pathway.....but for gutenprint it needs to have
                been designed for that version of gutenprint. It may take a few tries
                where you can not find your exact model listed. Good Luck!
                eg you have make Z model 142 so try model 140 then 100 etc
                cups also supplies generic models but these tend to be a bit limited
                Use the forum if you have any issues please.
