I can't find any Windows 10 drivers for the SII DPU-414. According to the Technical Details tab at , this thermal printer has drivers for Windows 2000, XP, Vista, 7 and 8. This suggests that the Windows 7/8 drivers are unsigned and will not work with recent Windows 10 versions. Microsoft insisted on signed drivers starting with Windows 10 Anniversary Update in 2016. (In 2016 there was a way to test an unsigned driver in Windows 10, see Google ("windows 10 unsigned drivers"). I don't know if these still work.)

I hope this helps. Filling out the form on the page Inquiry tab may let you get a link to the older drivers for the DPU-414. You can try using a virtual machine with Windows 7 or 8 under Windows 10 Pro or Enterprise, if you can find a license for the OS.

Dpu 414 stacks lines

Set SWDIP switch 1, switch number 4 to ON. That switch controls whether when you get a CR (Carriage Return), you get just that carriage return or a CR-LF (carriage return + line feed). You need the latter. Setting the switch to ON will accomplish that. Have a good day.

Access and clean the area where the paper runs over the heating/printing element. This area picks up foreign substances and bakes them so that the paper no longer makes proper contact with the print head. Use something like an alcohol based solvent to remove any build-up in this area.
