Woosim 4″ Mobile Thermal Printer PORTI-W40

Woosim’s well established 4″ mobile thermal printer PORTI-W40 goes from strength to strength.  Having been introduced some 15 years ago the W40 is still one of the most widely used 4″ printers within the highly competitive mobile printing markets, used by transport companies for delivery receipts as well as warehousing and hospitality applications.  The W40 is still one of the most compact and lightweight 4″ printers available today with dimensions of 138 x 88.5 x 45.2mm and weighing just 281g.  The printer has a UART(RS232 or TTL) interface (USB option) plus a Bluetooth Ver2.1 or IrDA Ver1.0 wireless connection offering great communication flexibility.  A 203 dpi or 8 dots/mm resolution allows the printer to support both text and graphics printing as well as QR and 1 and 2 dimensional barcodes. Drivers are available for Windows XP, CE, VISTA, 7, 10 and Linux plus we can supply SDK codes for ANDROID operating systems.
