kitlabels - print labels with barcodes and graphics on regular and label printers

Zebra Printer Notes:
  Under printing preferences, set label size under page setup - For 3.5 x 1 labels, you 
  would use New.. to initially create it. Other settings: Orientation: portrait.
  In acrobat, under file->print>properties to actual size, portrait.

OPTIONS:

    -p [ <printer name>, acrobat = send to previewer ]

EXAMPLES:

  Print 2 sheets of test labels on 8.5 x 11 paper to the acrobat reader:

     python kitlabels.py -s 0 -t 1 -p acrobat -v 1

  Print 1 4x6 test label: 

     python kitlabels.py -s 1 -t 1 -p acrobat -v 1

  Print 1 2.25 x 1.25 test label: 

     python kitlabels.py -s 2 -t 1 -p acrobat -v 1


NOTES:

  Takes input on stdin of the format:
  
  First token is one of [logo,barcode,keyval] 

  LOGO w/no arg renders logo512x512.png 
  LOGO C renders the a very large character C in its place
  BARCODE f1 f2 renders a barcode consisting of f1:f2, then renders 'f1:f2' underneath the barcode in plain text 
  KEYVAL f1 f2 f3 fn renders 'f1:' in bold, followed by 'f2 f3 fn', wrapping text lines if necessary

  See tgetl.testlines in source code for example input
