I have a LQ-570+ and had to renew all of the computers in my medical-office (family doctor)because Microsoft not any more supporting XP. But there is no driver for the LQ-570+ running under win 8.1. So I had to buy a new needle-printer for my third workplace and selected the LX-350. The quality of prints from MS-Word or other is bad, the letters unclear - not representative for my patients. Even worse are the prints of forms (e.g. prescriptions, advices, papers for the insurances or government with several copies). The printer is not able to communicate with my office-program. It is not possible to adjust the printer, that it uses the given fields (no problem with the LQ-570+ under XP). The printer LX-350 is useless for me.
