Scan related tags

Question

I think we need to sort out the following scan-related tags:

• scanner x 155

• scanning x 87

• printer-scanner x 9

• document-scanning x 5

• scan x 1

The rest are barcode-scanner, scan-disk and overscan which are alright and shouldn't be changed.

Now, from scanning tag wiki, I understand this is the one that refes to scanning a document/photo/etc using a scanner/printer scanner/etc:

Converting a physical document into digital form

So if we leave it that way, we need to merge document-scanning into scanning.

---

The scanner tag includes questions about scanning, printer-scanner and [not-printer-scanner] - so I think that if we leave only scanning and scanner then we should retag some of them questions in scanner and and merge printer-scanner into scanner, synonymize and add a tag wiki.
