Unix Pine can print to generic printers attached to ansi terminals.

Pine uses escape sequences on ansi/vt100 terminals.  "<ESC>[5i"
directs all output sent to terminal to the printer, then "<ESC>[6i" to
return to normal.

I have tried to implement this in the following script:

#!/bin/sh
echo "\033[5i"        #redirect terminal to printer
cat somefile    #send file to printer
echo "\033[6i"        #should reset terminal

The first echo works fine.
The file is sent to printer
The second echo *does not reset terminal output but rather continues
to output to printer so the "[6i" is sent to printer.

Clearly there is something I do not understand. Maybe this cannot be
done with shell script.

Any insights appreciated.

Andy

Appreciate all the responses. For the record here is what appears to
work:

----begin script------
#!/bin/sh
#script to send file to local attached ANSI/VT* printers
#tp
#ajg 10.6.96
#
if [ "$#" -ne "0" ]; then
  for arg in $*
  do
    if [ -f $arg ]; then
      echo "\033[5i"          # redirect terminal to printer
      cat $arg;                 # send file
      echo "\014"             # formfeed
      echo "\033[4i"          # reset terminal
    else
      echo "File $arg not found..."
    fi
  done
else
  echo "Usage: $0 filename [filename...]"
fi
#-----end script--------
