Hello Peter,
I very seldom write anything on paper nowdays but I've done some research to freshen up my memory.
pwr_foe_gre_print is used to print postscript files in the development enviroment, eg plc documents. It should contain a shell commmand to print out a postscript file and the name of the postscript file is added to the command. You can for example define it in $pwrp_login/login.sh with
export pwr_foe_gre_print=\"lpr -P lp1\"
where you replace lp1 with your printer queue.
pwr_foe_print and pwr_foe_print_land are used to print lists generated by the list function, eg crossreference or signal lists. These are written to textfiles which should be printed in portrait or landscape format. They are defined in a similar way as pwr_foe_gre_print.
In runtime you define pwr_rt_print, and, if you have a special color printer, pwr_rt_colorprint. It should also contaĆn a shell command to print a postscript file. It can be defined in the startup-file for rt_xtt.
