Not suitable for 4" wide printing because this is a 2" wide printer. See LP 2844 or TLP 2844 if you need a 4" wide version.

LP 2824 and TLP 2824 prints up to 2" wide (i.e. 1" wide labels, 1.5" wide labels, 2" wide labels). Great if you only need labels that are never more than 2" wide.

TIP: You could print 4" wide labels (or even wider) if you printed them sideways. But 2" wide x 4" high labels are not common. What you need is an LP 2844 or TLP 2844 (i.e. the 4" wide version).

8 dot means 203 dpi - ideal for bar codes and text (it's what everyone uses)

Thermal Transfer means you can use ribbons to print on to plain ordinary paper labels (or materials like plastic). Wax Resin ribbons (a mix of wax and resin) are recommended for printing on to paper - for clear, sharper printing and scratch resistance.

Thermal Transfer models don't have to use a ribbon if you use Direct Thermal labels - labels that go black on there own when heated.

Direct Thermal models cannot use a ribbon, cannot print on to plastic and can only print on to Direct Thermal labels - labels that go black on there own when heated.

Why would you need a cutter? The cutter options allows cutting in to easily identifiable sets of labels (i.e. you could print and cut 100 sets of 2 labels - so you'd have 100 bits of paper each with 2 labels on). For example, if every 2 labels had the same number (one to be stuck on a box and one to be stuck on a corresponding item to go in the box) if you printed 200 labels in a big strip, people sticking the labels could easily get out of step and disaster.

Why would you need a peel option? If you are busy sticking labels on things at a desk or bench or conveyor belt even, you can label things much faster if someone hands you a sticky label already peeled - that's what the peel does - if allows you to take the label and stick it - you don't need to remove the backing paper - you could stick labels at 1 per second. It works because the printer knows when you've taken the last label, and even if you told it to print 1,000 labels - it waits till you take the last label and then instantly print the next, ready for you.
