We think it would be a good idea to have Rock automatically add ~JSB to a check-in label ZPL when a cutter is in use (meaning, the client is set for "Enable Label Cutting" or the Printer Device in Rock has "Has Cutter" enabled.

The problem being solved is this: The default labels in Rock use ~JSN, which tells the printer to backfeed AFTER a label has printed, which is great for non-cutting printers, but on a printer WITH a cutter, ~JSN causes:

• The label prints, then the printer backfeeds and the next label rests on the rubber platen
• This induces a curl into the label in as little as a few hours, but definitely after a day of non-use
• The next time the printer tries to print, the now-curled label jams going into the cutter, causing check-in chaos.

In contrast, by automatically using ~JSB when a cutter is in use:

• The label prints, does NOT backfeed, and the next label rests WITHIN the cutter.
• No curl is induced.
• The next time the printer tries to print, the label backfeeds, prints, and is again parked in the cutter.

I have personally seen this issue brought to Rocket.Chat support MANY times, and the fix of editing the label and changing ~JSN to ~JSB always solves the jamming problem. It would just be great if Rock did this automatically when it knows a cutter is in use.
