Labeling Software

Because Inkjet and Laser printers are in such widespread use, labeling software

to make these printers capable of printing bar codes has become readily

available. There are two general types of bar code printing programs available:

1) Menu-driven programs for operators to design and print labels.

2) Bar code font programs to allow printing of bar codes within

other Macintosh or Windows programs. No programming is

necessary by the user.

Stand-Alone Menu-Driven Programs

These programs allow the user to design different label formats and save them to

disk for label runs. Usually there is a WYSIWYG design interface to view the

label on screen as it is being designed, especially Windows programs. These

programs usually have most of the following features: scalable fonts, graphic

image import, all popular bar codes, data file import, easy custom operator

interface, popular data base access, and/or built-in label data base. Look for a

program that doesn't combine support for laser/dot matrix with thermal transfer.

Separate programs for common PC desktop printers vs. thermal transfer printers

keep it simple for the user.

Besides the ability to design and print labels, you should look for a program

with a simple operator interface. The label designer creates custom prompts for

a label format; then the operator answers simple questions that lead him to enter

the variable data for the labels to be printed. With a label database, you can

select which labels to print. You don't want the operator to have to deal with the

more complicated label design screens.

Font Programs

In the Windows and Mac environments, any font-based program can select fonts

for printing. This makes it possible to use bar code fonts from such programs as

Word, Excel, PageMaker, Quark, etc. Problems include:

1) Scaling - When scaling, Windows and the Mac can make little

adjustments that really mess up the bar codes. Most programs

give you fonts at a certain point size and density that are very

accurate for the printer they were designed for, however, if you

change printers or change point sizes, anything can happen. Be

careful when straying outside the standard point size for printer

specific fonts.

2) When printing UPC, a 0 can be represented by four different

bar/space patterns, depending on where it is in the code and

the computed parity of the data. Therefore it is necessary to

have a translator program to switch to, enter the data you wish
