410659 2005-12-12 04:59:00 How about taking two USB to Printer leads, chop off the printer end of one of them & splicing the cut end into the other. I Imagine it would work. BUT, Would two computers like trying to get at the same printer be confusing? What about 'feedback' , down one USB Comp along to the splice & up into the other USB Comp? Wouldn;t that cause problems?? PJ Poppa John (284)

Stop imagining PJ.

410661 2005-12-12 06:18:00 Note it says USB 1.1 also.

I'm happy to stand corrected, but USB2.0 is probably hype in relation to a printer. I doubt whether printers utilise full USB2.0 data rate. Since USB2.0 is backward compatible, and physically the connectors are the same, then a USB1.1 switch can be happily plugged into USB2.0 computer ports, and into a USB2.0 printer.

I realise they are backward compatible,but was unaware that printers didn't benefit from extra USB2 speed.Learning something every day they say is good for you. :)

410664 2005-12-12 07:05:00 I may well be wrong, but I can't imagine a normal printer shooting out pages at 480Mbps :)
I suspect the reason printers are now specified as USB2.0 connectivity, is that computers now only have USB2.0 ports.

410665 2005-12-12 07:15:00 Also keep in mind that there are 2 forms of USB2, Full Speed and high speed.(and I always forget which is which....)

And in a cunning move, one of them is actually just USB1.

This move enabled all the manufactures to rebrand their USB devices as USB2.....

Very confusing for someone who starts out confused.

But I do get some pleasure in my new ip4200 spitting pages out like there is no tomorrow. :)

Because Poppa, USB isn't just a cable . That wouldn't have worked with a parallel port, or a serial port either, and they are much simpler interfaces .

When you plug a USB device in, lots of things happen . The computer's USB controller notices there's "something" there . It says "who are you? " . The controller in the device says back "My Vendor ID is 1124, my Product ID is 4A92, I am a printer, I draw 1 unit of power, the maximum speed I can communicate at is . . . " . The controller tells the OS " I have a USB device here, its VID and PID are . . . " . The OS thinks, "have I got a driver for that device? " . . .

After all that (and more) you can use the device . It goes through a couple of levels of this if you have a USB hub between the computer and the device . . .

Each USB device has to have a port on a controller, all to itself .
