How to modify /etc/printcap?
I put this on the CentOS forums yesterday and it's been read 80 times, but no response..........I hope I'm not too impatient.

Hello,
I am trying to set up a 3 port HP Jetdirect 300x box. I have done the following:

Added jetdirect to host file with IP address.
Created 3 printers with lpadmin (one for each port).

Now I'm stuck. In SCO UNIX, you can just modify the rm variable in the /etc/printcap file to route print jobs to the hostname, however with CentOS, I cannot change that file because it will be overwritten by cupsd and the /etc/cups/printers.conf file doesn't have the rm variable there. Where can I make this change permanent? I did try lpoptions and it created an lpoptions file in /etc/cups with the variable that I added, I don't know that this is what I want to do, unless it somehow is read at the time a print job is sent I don't think it will work.

I did find that I could shut down cupsd and remove the startup script from /etc/rc5.d, which would then stop /etc/printcap from being overwritten, but this is going to cause problems because cups won't be running and then nothing will print.

Any help would be appreciated, I have checked Red Hat docs, CentOS, Googled, etc and all I can seem to find is how to do this via GUI interface, not command line. I've seen where it clearly says that you "cannot edit /etc/printcap", but not where it says what to edit to change the rm variable.

Thanks,
Nick

Apparently there is no easy way to modify /etc/printcap to change the rm variable.

An associate of mine found something on an old forum that might work for the Jet Direct 300x...............the first printer on the box will be port 9100 and subsequent printers are on port 9101 & 9102.
So,
lpadmin -p testprinter1 -vsocket://192.168.10.10:9100 -E
lpadmin -p testprinter2 -vsocket://192.168.10.10:9101 -E
lpadmin -p testprinter3 -vsocket://192.168.10.10:9102 -E

I will have to test to confirm if this works.

set_color

set_color(1)							       fish							      set_color(1)

NAME

       set_color - set_color - set the terminal color

set_color - set the terminal color
   Synopsis
       set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR]

   Description
       Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple,
       cyan, white and normal.

       o -b, --background Set the background color

       o -c, --print-colors Prints a list of all valid color names

       o -h, --help Display help message and exit

       o -o, --bold Set bold or extra bright mode

       o -u, --underline Set underlined mode

       o -v, --version Display version and exit

       Calling set_color normal will set the terminal color to whatever is the default color of the terminal.

       Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey
       font color, while set_color --bold white will result in a white font color.

       Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator.

       set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and
       incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of
       ncurses and recompile fish against it in order to fix this issue.
