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

Question

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.

Answer 1

Common features required would be single or dual WAN, VLAN support (at least 4),
With a minimum of 4 VLANs, the 860 is out of the question as this model can support only 2 VLANs.   The 880 can support up to 8 VLANs.  Now both the 860 and the 880 has a 4-port, FastEthernet, layer-2 switch. The 890 can support up to 12 VLANs and have an 8-port, FastEthernet, layer-2 switch at the back.
Now all the models mentioned, 860, 880 and 890, can support PoE.  The 860, 880 and 890, can support 4-ports of PoE.
I've two vital questions for you.  They are:
1.  Are you planning to integrate your wireless with your router?
2.  What is your bandwidth?
If you plan to integrate a wireless access point with your router, you need to be mighty careful with this.  The reason is because of the potential location of the router in the premises.  Most of the time, the router is located in the far corner of a property and inside a metal box/cabinet.  For starters, the location is far (to very far) from the clients so the wireless signal is propagating to no one.  Next, if it's inside a box or a cabinet the metal shell of the cabinet can disrupt the way wireless propagates.
This is the reason why I mentioned the PoE option.  If the location is similar to what I've described, then it's better to get a router AND WAPs separate.  This way you can move the WAP to wherever your clients might be.
Next is your bandwidth.  What router to buy depends on what bandwidth you've got.
