Windows programs usually give you rich text fonts, more rotations, and

excellent image graphics printing. The labeling programs for Windows often

support Postscript printers.

Ink Jet Printers

These printers are getting better and better. They print pages of labels, so refer

to the page label stock discussion below regarding page laser label stock. Also,

use label stock specifically meant for inkjet printers – the stock is usually coated

to minimize ink bleed. Always test your bar code labels for readability before

printing in bulk.

Inkjet printers are almost exclusively supported by Windows programs. If you

have problems, check to make sure you are using the latest driver version from

the printer manufacturer. Also, be sure to select a printer that has a separate

black cartridge in addition to the color cartridge.

If labels you are printing are going to be exposed to water, don't use the inkjet

printers – most inkjet ink is water-soluble. Inkjet printers are NOT the best

printer to use to print labels that need to withstand the weather or are subjected

to constant scanning.

Beware; the inkjet cost per page in color is twice cost of a black and white print.

Thermal Transfer Printing

Thermal transfer printers are required when you need either to print one label at

a time or when you need to print a roll of labels so that labels can be applied by

applicators directly to boxes. Volume industrial label printing is done mostly by

thermal transfer printers. They are fast and produce excellent quality bar codes.

Thermal transfer refers to the printhead heating up and melting a ribbon onto the

label surface. Most thermal transfer printers can also produce "direct thermal"

labels, but paper instead of a soft ribbon wears out the printhead 10 times faster;

another disadvantage of thermal printing is that most thermal labels cannot be

read with IR light and deteriorate in sunlight to non-readability over time. The

media cost is about the same as laser and direct thermal. Thermal transfer

printing is far more popular than thermal printing for serious label production.

Beware of the CoStar and Seiko thermal printers for producing serious bar

codes. They have two problems:

1) the bar codes are just a little off, (the naked eye can often see 3 sizes of

bars when only two are supposed to be possible), and

2) There are thermal printers producing bar code labels that deteriorate to

unreadability in sunlight. They are inexpensive, thus very attractive, but

beware.
