Amazon affiliate link in GitHub is a different printer

[philcunliffe]

The amazon link to the printer takes you to a listing with model number MC206H which seems like it will work but differs from the listed CSN-A4L

I bought and used the linked MC206H printer. It worked perfectly for me with no modifications necessary. It seems like it uses the same instruction set under the hood. Attaching the reference materials from the seller in case you need them.
