Printer and Barcode Scanner Requirements

 

Printers

There are several manufacturers of printers and different kinds of barcodes and paper to adapt to different use cases. Most manufacturers have their own proprietary printer driver and language for labels.

To allow freedom of choice for the barcode printer, the openBIS ELN-LIMS allows to configure both the type of barcodes and the layout and size of the labels. openBIS uses this information to produce a PDF document, thus having as single requirement that the printer driver used allows to print PDF documents using applications such as Adobe Acrobat Reader or Preview (Mac).

 

Printer Configuration

There are different types of printer drivers. The two types we can define as generic are PS (PostScript) (recommended) and PCL (Printer Command Language). Printers with these drivers are likely to print PDF documents and other types of documents with embedded fonts, images, etc…

The printer paper type needs to be configured for each printer. Two layouts are supported:

  • Split: The PDF will contain separate pages with each barcode.
  • Continuous: The PDF will contain a continuous layout with the barcodes. More uncommon for this applications.

The printer paper size needs to be configured for each printer. It is possible to indicate the size of the barcode, so it can fit.

 

Printer testing

We provide two example documents that can be used to test the printer.

 

 

Please consider that these examples likely do not correspond to the particular paper size of the printer being evaluated and as such the barcodes may look squashed. In order to obtain optimal results, the paper size would need to be configured. However, for the test it is enough to verify that the printer can print those files.

 

Printer Advice before purchasing

Before purchasing a printer, we recommend to check with the manufacturer that the barcode printer provides a general driver and that it can print one of the documents provided as example above.

 

Tested Printers

  • Zebra ZD420

 

Scanners

There are several manufacturers of barcode scanners. In most cases scanners act as a keyboard for the computer, so when the barcode scanner scans a barcode it will type whatever has been scanned.

 

Scanner Configuration

The scanner keyboard layout should be the same as the computer used. If not this could cause problems if there are any special characters.

 

Scanner testing

Open a notepad and scan the barcodes provided in the examples below. The scanner should read them and type the correct output.

 

 

Scanner Advice before purchasing

Before purchasing a scanner, ensure that the barcode scanner provides a keyboard driver and ask the manufacturer’s support to scan the examples above.
