I would like to connect a Canon BJ-10sx to a Windows 8.1 64bit laptop.
The printer has a parallel input, for which I have a USB to parallel
converter. The converter works fine for another printer which declares
its name.

There is no 64bit driver for the Canon, but I have installed a driver
for another printer which should work with the Canon. But as the Canon
can't send back data to the computer, the computer can't recognise it
to match with the substitute driver, the parallel port LPT1: does not
appear in Control Panel, and "No printer attached" appears under
Universal Serial Bus Controllers when the adapter is plugged in.

Is it therefore impossible to connect this Canon?

Dunno if this is any help but, disregarding the serial-parallel issue
for the moment, I have a printer that is an absolute sod to connect to
Win 8.1 but when I slip a Linux live boot disk in the machine, Linux
just finds the driver it wants on-line and gets on with it. Worth a
try?
