Does anyone still make a monochrome office printer with true Postscript?

I'm looking for a monochrome laser printer to print letter-size paper, with true (not emulated) Adobe Postscript. The discontinued Xerox Phaser 4510 could, but its replacement, the Phaser 4622, has emulated postscript. Some Xerox color printers have true Postscript, but I don't want or need a color printer. The monochrome Phaser 5550, which can print up to tabloid size, is larger and more expensive than I need.
