Microsoft standard device drivers are utilised by the Display program, which makes for a large list of supported printers. Logs are generally printed on continuous A4 size, fanfold paper at any scale and presentation style required by the client. Printrex thermal printers are used in the field to print on fanfold paper. Logs can be supplied also in .las, .tiff and .pdf formats if required, on CDs and via email.
