ZEBRA COMMAND LINE RFID PRINT UTILITY Needs some cleanup work, but this handy script lets you execute simple print commands to a Zebra RFID printer that is connected to your computer.

// RANGE EXAMPLE prints range to screen only:

//
// RANGE EXAMPLE prints range:
//    C:> node zebra zebra 1 100 "" print
//
// CSV EXAMPLE displays CXSR.csv regardless of start or end, NO PRINT:
//    C:> node zebra zebra 1 1 CXSR.csv
//
// CSV EXAMPLE PRINTS CXSR.csv regardless of start or end:
//    C:> node zebra zebra 1 1 CXSR.csv print
