This switch works in the printer mode, unfortunately, limited. With my Epson DX9400 not. Printer is addressed - but then has a spooler problem. The pages are printed but when the computer shuts down. Scanning also goes only on the scan mask of Windows - non-Epson. OK Digitus can not - stand there but then again the problem after half an A4 sheet is the scanner. Without USB Switch no problem. (Win7)
Can not recommend this switch. Have ordered a mechanical switch - no problem.
I think for pure standard printing applications works - hence the 2 stars. SW is also OK.
