Parallel printer requires constant re-inserting into USB hub

[rh0000]

I have a Toshiba laptop running Vista home basic. I use an HP laserjet 1100
parallel printer which I plug (via a USB-to-parallel converter cable) into a
USB hub which feeds into one of the USB ports on my laptop. Very often, when
I try to print (Word document, web page, pdf file, anything) nothing happens
until I remove the converter cable from the USB hub and then reconnect it.
After I have done this, the printer will then work fine from then on, but
will then stop working whenever I reboot the computer. If, when I reach the
point at which "nothing happens", I remove and rejoin the converter cable
from the printer cable, or remove and rejoin the printer cable from the
printer, that doesn't solve the problem. And if I have an extension USB cable
joining the USB hub to the converter cable, and remove and rejoin the
converter cable from the extension cable, that doesn't solve the problem
either. The only thing which works is removing the cable from the USB hub and
then reinserting it, and this usually works every time. It's not a big
problem, but it's irritating to have to scrabble around about the cables. Any
suggestions as to what is going on and how I might be able to get my printer
to start each time without having to fiddle about with the leads?

Does this combination (USB conversion to LPT cable, HP 1100) work on another
machine (XP)?

Is the USB hub powered? Make sure the USB ports on the laptop are
configured such that they don't go to low power state.

The next thing to do is ask HP if they recommend a specific USB to LPT
conversion cable for this device. Most likely they will tell you to get a
newer USB device but you can try.

A docking station with LPT port could be one solution but I've seen docking
stations that connect to USB and you are back in the same boat. A network
print server device for LPT printers is also another option.

Alan pretty well covers it. However, I am wondering if the problem persists
with a direct connection between USB-parallel converter cable rather than
through the USB hub. As well, in this connection, I also wonder if the USB
hub is independently powered or draws its power from the USB port.

Thanks for your reply. I don't have access to any XP machine, only my Vista
laptop. (My previous PC ran Windows ME and had a parallel port.) The
difficulty arises whether I use a powered or unpowered hub. I will look into
whether HP recommend anything, but it's odd that my USB to parallel cable
works after it has been inserted into the hub, but not before, so I would be
surprised if a different cable achieved anything. Of course, as well as using
the USB to parallel cable, I also need a parallel to "mini parallel" cable,
because HP parallel printers use this funny small parallel plug and socket.
