most mid range onwards laser printer can handle the job you requred.

be it "Paper (bond, light, heavy, plain, recycled, rough), envelopes, labels, cardstock, transparencies, heavy media"

for best result you need to test around differents setting above with your media.

My recommendation are go for those printer with multi purpose tray, with rear door without sensor so it will still operate while it left opened. With this setup your heavy media will not bend from feed to output = you get best result.

Only mid range laser printer comes with 2 tray (tray 1 = the multi purpose tray & tray 2 = the cassette tray)
I not sure if there is sensor at rear door for this model, you may check with HP directly, ask them if the printer can operate if the rear door left open.

this is typical paper path in a laser printer, feed from bottom (the cassette tray), output at the top


this is what I recommended


Anyhow, with this method you can't print too many papers with one go as the limitation of multi purpose tray load & the opened rear door won't hold any output paper, means you need to pick your printed job from the floor unless you modify something to hold the paper.
