Data output

[Emile van Sebille]

Here are some excerpts from a zope based label printing
utility I set up last year under winnt work station:

 if REQUEST.printLoc == "California":
  printerID = r"\\nova104\weber"
  printerDevice = "LPT2"
  outFile = r'f:\CA_Label.txt'
  batFile = r'f:\CA_Label.cmd'
 elif REQUEST.printLoc == "Illinois":
  printerID = r"\\shipping\webera1"
  printerDevice = "LPT3"
  outFile = r'f:\IL_Label.txt'
  batFile = r'f:\IL_Label.cmd'
 elif REQUEST.printLoc == "None":
  printerID = r"\\fclt\weber"
  printerDevice = "LPT2"
  outFile = r'f:\FX_Test.txt'
  batFile = r'f:\FX_Test.cmd'

######### and the later....

 osCommands = [('net use %s: /DELETE' % (printerDevice,)),
   ('net use %s: %s /PERSISTENT:YES' % (printerDevice,
printerID)),
   ('copy %s %s:' % (outFile, printerDevice))]

 if problems:
  return string.join(problems,'\n')
 else:
  printer.flush()
  printer.close()
  batch = open(batFile, 'w')
  for eachCommand in osCommands:
   batch.write("%s\n" % eachCommand)
  batch.flush()
  batch.close()
  os.system(batFile)
  if REQUEST.printLoc == "None":
   return
"Submitted!\n\nReprinted:%s\n\nSequences:%s\n\nLines:%s\n\nR
EQUEST:%s" % (repr(rePrintSeqs), repr(assignedSeqs),
db_repr(lines), repr(REQUEST))
  else:
   return "Submitted!"




Hope this makes sense.  :-)
