Driver for the OKI 4w and compatible winprinters
------------------------------------------------

These laser printers have neither memory nor a processor and therefore
they must get their data in an absolutely continuous stream (because
they cannot buffer data). This cannot be made sure by usual printing
spoolers (as CUPS or LPD). The only possibility is running a special
driver program which connects directly to the printer. But this is
very unconvenient, because many Linux applications can only print
through a spooler. To solve this, Grant Taylor has created a special
daemon acting between the printing program and the spooler, the
"oki4daemon". It provides a named pipe ("/dev/oki4drv") which accepts
PostScript and renders it for being understood by the printer.

Because "kups" and the web interface of CUPS cannot start an extra
daemon and also cannot set up a queue with "/dev/oki4drv" as
destination, you have to install your OKI printer with a special
installation program. Call it by entering

   oki4w_install

on the command line or by choosing "Configuration"/"Printing"/"Install
OKI 4w or compatible" in the desktop menues.

NOTE: These printers should not be used on machines which are often
under high loads (because of the timing requirements) or on machines
with high security demands (because of the additional daemon).
