One-at-a-time Mailing Label Printers? by Addressing-Singles Dept.

An anonymous reader asks: "I work at a small law firm, and we are looking for a better way to print mailing labels. Currently, we print out an entire label sheet (30 labels) for each of our regular clients, storing them in binders. For one-offs, we use a typewriter. I'd like to find a label printer for around $250 (or less) to print labels one at a time. The challenge is that all the printers I can find are thermal print. Our fear is that a label may become unreadable due to heat exposure sometime during mailing. Even if label damage due to heat is rare, we cannot afford to take a chance since many of the documents we mail are time-sensitive. Also, we often send documents unfolded in large envelopes, so addressing #10 envelopes through a laser printer isn't enough -- we need labels!"
"The ideal printer would be non-thermal, e.g. inkjet, available through our network so anyone could print from their desktop, usable with some network printing device, and maybe even compatible with our Samba print server. Oh yeah, and I'd like it to be open enough that I can send text to it for printing, so maybe I can write a quick app to let users print labels from our client database, or make their own on the fly. Finally, I'm hoping to find a product that is not discontinued (e.g. Seiko EZ30), as surfing eBay for office equipment is not something my boss is willing to let me do."
