[thelist] PHP LPT1 Question

[Scott Harman]

Very odd! ;)

I'm guessing you want a teleprinter type operation

http://www.php.net/manual/en/ref.printer.php

By single byte I'm guessing you mean unicode character?
There shouldn't be any reason why you can't open connection -> do stuff
(print bytes) loop until done -> close connection

You're talking about manipulating a spool rather than a printer, but
it's theoretically the same - this way you could presumably write all
form field inputs simultaneously to a db and to a physical archive?

It looks like it may only be supported under windows

The comments outline it all quite nicely

Subject: [thelist] PHP LPT1 Question


I've got a little side project I'm working on involving some custom 
hardware plugged into the printer port (LPT1).  In a fit of sheer 
madness I've decided to attempt to write the software for this thing in 
php (yes i know, its nuts). 

Okay now for the real question, is it possible to send single bytes of 
data to the printer port with php?  From my testing thus far i've been 
able to send entire strings, but i don't have the equipment setup to 
test sending a single byte.  Anyone have any thoughts? ideas?
