Does anyone have any idea on the size of the i/o buffer on an ntx? I know
it's gotta have some since printing a banner page from an idle printer
takes longer than from a printer that is currently processing. It must be
due to the computer loading the buffer while the printer is finishing the
last job.
Basically what I'm doing is re-writing BSD lpd to recognize when a printer
is a LaserWriter and when it is, it'll ask it if it has various data in
it's dictionaries. If the data is there, it can just print normally, and
otherwise it'll upload a file to install the needed data. This data can
be something like local fonts or a banner page. Something that's used
often enough that should only be uploaded once. The problem with this
is that since the daemon is asking a question, it can't start filling the
buffer until it gets an answer. I want to know if the lost time will be
made up in not loading the data with every print job.
