In another instance, take the case of ticket checkers in public transport vehicles like city and inter-city buses. Most such buses are always full, more so during rush hours. Till a couple of decades back, the conductors used to issue tickets from the bundles of pre-printed tickets of different value denominations, which was quite a slow and frustrating job. Today, most bus conductors are provided with POS billing paper printers, especially thermal paper printers. This has speeded up their operations and improved their efficiency.

Rudkav International are dealers of POS billing paper rolls in two types – plain and coated bond paper and coated thermal paper. While the printing on the plain bond paper takes place through ink impression on an impact printer, the printing on thermal paper takes place through heat transfer. This is because the thermal paper has a specialized chemical coating on which the application of heat enables the printing on the coated substrate with just the head and nothing more. We supply the thermal paper that is not coated with BPA (Bisphenol A), a chemical compound that has been found to be hazardous to humans.
