That looks like the screen display on my fish finder.

Yeah, wouldnt care to try with HTV. I doubt the laser could produce enough heat, long enough needed for adhering, without vaporizing it anyways.

From everything Iāve read, Most if not all Heat Transfer Vinyl is safe to laser. The name isnāt really accurate, as it throws people toward thinking it is laser toxic like other adhesive vinyl. I also donāt think it would adhere with a laser. While heat is probably a problem without vaporizing, pressure is also a big component of good adhesion. I might cut some on the laser, but only designs that are one piece so that I can cut through. Then use my heat press to adhere.

Yep, thereās been a thread somewhere on laserable heat transfer not-vinyl. But all about cutting/engraving the patterns before putting on a shirt.

KITTEH!
The heat-transfer films that I use look exactly like vinyl when on the roll. Generally a PU material. It cuts nearly the same as vinyl does on my plotter, and come in many āflavorsā (stretchy, shiny, glittery, metallic, matte). Some of them are a pain in the tookus to work with and some of them are an absolute joy. One thing to keep in mind is that it requires heat and pressure apply to materials.
I would worry that some of the more stretchy films would react badly to cutting with heat (shrinking) but those are often on a adhesive backing, which might help keep everything in place.
The materials can handle some very good detail, although weeding intricate designs is a chore, and they absolutely do not last forever. The films also donāt do a great job when fabric shrinks or stretches over time.
The lasered designs on fabric should last the life of the fabric, stretch and shrink with the fabric, and require no weeding! For one-color designs, I think it could be incredible. Canāt wait to play. Also curious about what it does to various dark fabrics. Will a lasered design on a black t-shirt show up as white-ish (bleaching of the dyes) or pink/purple (whatever the base color used to make the black), or will it seem invisible?

Good point - I almost forgot the second half of the name āheat pressā (and I have one ! 
)

When you āde-focusā the laser, is that simply changing the bed height from the focus level? You donāt actually adjust the beam itself or set it in software do you ?
OH never mind - I saw this answer in Ryans āHello Worldā threadā¦

I am thinking that moistening the fabric might be the way to go for better control of not burning the fabric too deep. Also being able to do this with a a heat set dye or ink if there is any such thing would be awesome.

@smcgathyfay has done some experiments with using laser printer toner powder in her cutters. I donāt know how well it would sick to fabric, but itās worth a try.
It only worked when I engraved a deep pocket to put it inā¦cant really do that with fabric so I dont see it working in this caseā¦needs a thick layer

I just have trouble seeing laser toner and fabric working together that well (unless going through the laser(printing).
