Using surface pro and dnp ds40. Problem I have is every time I plug printer in, it make a new DS40 printer file. As in DS40, DS40 copy 1, copy 2 and so on. I have to find which one is the online printer and select that one. While using at an event, it will actually stop printing. I have learned that during an event, it will actually switch the printer file it is using putting me at a stop. Then I have to go into printer settings and find the active printer file and switch to that. I am using a multi plug USB as my surface only has one port. DNP customer service says that is to be expected. Was told I can not use a multi port usb hub. Also told that the DS40 is NOT to be used with a tablet. She also told me that no one uses a table for their photobooth. really? Anyone else having this problem?
