SQR Viewer not printing from different printer trays

[Rochelle Martin <rmartin@TRIBUNE.COM>]

     My SQR report needs to print from different printer trays but also
     needs to be in SPF format. I have added the "encode" logic suggested
     from a previous mailing.

       encode '<27>&l4H' into $low_tray
       print $low_tray () code

     This works perfectly when the .LIS is sent directly to the printer but
     not when I print the report via SQR Viewer.

     Suggestions for fix or explanation on why this is happening would be
     great.
