Lexmark T640 Monochrome Laser Printer Review

I installed this printer a year ago at a non-profit I work for. It has a couple of gotchas, which caused us massive grief for a few months.
If you print via the Internet Printing Protocol (IPP), the printer will crash periodically on seemingly random jobs. When it crashes, it doesn't automatically reboot. Reconfiguring your print server or desktops to use the LPD (or other protocols) will fix the problem. Lexmark has all but forgotten about this printer, and hasn't offered a software update since May of '07, and the frequent crashes are not addressed on their support site, but *are* mentioned all over the internet. :-)
We are a PostScript based shop (but really just print Word and Excel documents), and this printer's emulation software is adequate, but unbelievably slow. I wrote some simple PostScript test pages which fly out of our other printers, but not the T640. When warmed up, time to first page varies from 5 to 60 seconds.
The printer is *very* eager to print. The moment a print job starts downloading, the fans, rollers and drum fire up in anticipation. Then they shut off twenty seconds later because the PostScript interpreter hasn't finished rasterizing the page. It makes you get up from your chair ("It's printing!") only to fake you out. :-)
Generally, PostScript benefits from having more available memory, so I added 512MB to the thing, and it really didn't make much difference.
So yeah, the printer does what it's supposed to. Just slowly.
