I'd like to buy a Sipix A6 portable printer for printing boarding passes on the go since they can be had for around $20. It is said to work in Linux:
http://openprinting.org/show_printer.cgi?recnum=SiPix-Pocket_Printer_A6 but that page only mentions the serial connection and doesn't mention the infrared connection. If it's working via serial, should it also work via infrared? If not necessarily, should it definitely work via a serial->USB adapter that works in Linux? - Grant
