3.3.3 Printing bar code
Printing readable bar code depends on various factors that need to be
taken into consideration in order to achieve results suitable for reliable and
durable archiving. The main factors influencing the bar code results are:
• printertechnology
• howthebarcodeiscreated
• thetypeofobjectbeingprintedon
• thetypeofscannerusedtoreadthebarcode
Printer technology
• Asadotmatrixprinter,theIPScanhandleinformationonlyintheform
of dots printed or not printed. It is not possible to transmit bar code data
or to select specific bar code types or use the printer to create and print
the bar code required.
Creating bar codes
• Sincethereisonlylimitedprintingspaceontheslides,thebarcode
should not contain more information than necessary.
• Youshoulduseanerror-checkingcode,whichmakesiteasierforthe
bar code scanners to recognize possible errors. Some codes even sup-
port error correction.
• Whencalculatingandcreatingbarcode,alwaysbearinmindtheresolu-
tion of the printer.
The module size is the width of the smallest element of a bar code. Wider
bars and spaces are calculated in multiples of the module size.
The module size always has to be an entire divisor of the printer resolu-
tion, as, due to the technology applied, only 'whole' dots can be printed.
Reading errors may occur (even if the print appears to be crisp and cor-
rect), if, due to conversion, module width and resolution do not match
any longer.
3. Instrument Components and Specifications
Data should never be printed as bar code only, but also as text
(line of optical characters above or below the bar code), to ensure
that no information is lost for the above reasons.
