Should I split a long reference into lines myself?

No. Enter one continuous reference; the encoder chooses the number of rows. If the content exceeds capacity, shorten it or use another format supported by your system. Choose Code 128 for a single-row label or QR for a phone-friendly web link. Keep all rows and white margins intact, and test the final-size print.

How do I check the code before printing?

Leave the white margins intact, keep the image in proportion and scan a sample at its final printed size with the device you intend to use.

Using Code 16K

Code 16K, also called USS-16K, packs data into 2 to 16 rows of bars. It can save width compared with a long single-row barcode. It is not a QR code or several separate Code 128 labels. Use it when your scanning system supports Code 16K.
