Launch a batch remote command via /putty ssh and get the output in a local file

Really sounds like you'll want to look at rsync. See Backing up Windows machines using rsync and ssh by Manu Garg.

Economical backup solution: rsync and ssh

As all other unix tricks this is also the result of laziness and the need. I wanted to backup data on my windows laptop to a central linux/unix server. I didn't want all the features of available expensive backup solutions. Just a simple updated copy of my data on a central machine which is backed up to the tape daily. rsync is known for fast incremental transfer and was an obvious choice for the purpose.

Try using the -w option:

From the MAN page:

 -w      Use 132 columns to display information, instead of the default which is your
         window size.  If the -w option is specified more than once, ps will use as
         many columns as necessary without regard for your window size.  When output
         is not to a terminal, an unlimited number of columns are always used.
