I just purchased a NUC6i3SYH. I have attached everything but having a problem finding the correct cable that is needed to plug into my new unit as well as my HP printer. What size, etc.?
Assuming a MODERN printer, you need a USB-A to USB-B cable of the length you want.
HP, saving every penny they can, do not provide the cable. But, somewhere in their documentation, they will tell you what cable you need.
Provide the printer model number and we may be able to help more.
Well, I faced the same issue for now. I think that it's all about the cable or maybe new OS I've started using recently, cause I've never had such issues on another PC. I've recently have purchased this color label printer in canada from this online store, which is maybe the best place to get printers and blank labels. They have pretty reliable service, I should say.
And, if you wish to connect a really, really old HP printer, you need to procure a Centronics to USB cable. Here is an example of such a (US$9) cable: https://www.amazon.com/Sabrent-Parallel-Printer-Adapter-CB-CN36/dp/B00IDU0T1Y.
Hope this helps,
