Printing PS Text Error

[nigelkf]

I am trying to use PS to display our company logo on some documents. The graphics work fine drawing the 'pretty' bits. When I tried to add the words to the graphic everything stopped working. I tracked it down to just this section which does not work, it does not produce anything on the printer.

%!PS
/Courier findfont
12 scalefont
setfont
(tgb) show
showpage

If I view the result in Ghostscript and GS View I get the following error message...

===error message starts===

Since this code is taken from one of the online PS tutorials i don't see what the problem is. Any suggestions will be thankfully received.

Hello
just add "x y moveto" (with x ,y position of your text)
before your code,
PS needs to know where to write
