USB to Parallel conversion requires translation by XP and Vista's
'hardware interleave' software as well as the USB device manufacturers driver.
The software package just doesn't work well with older peripherals that use
legacy parallel or serial com ports. Too many sloppy layers.
THE BEST WAY to add an LPT
printer port to your laptop is to use a PCMCIA to Parallel adapter card.
The PC Card slot provides access to the laptop's data bus, and the PC Card
adapter easily sets up as a native LPT port within almost any OS.
There is no delay, or connection problems as I've seen in so many
complaints about USB to Parallel or Legacy Serial adapters. Printing
PCMCIA is a mature standard, and works seamlessly with XP and Vista,
and almost any other OS.
PARALLEL is the old standard fast data protocol. IEEE 1284 ECP mode up to 1.5
The BJC-80 and the BJC-85 have the same print speed. The
BJC-85 just added USB.
INFRARED is ver 1.0 on the BJC-80, and printing is a bit slower at 115.2 kbps.
Even the BJC-85 with its higher IRDA transfer rating and a laptop's built-in IR
port, the XP print spooler has problems with it, and can hang if printing more
than one page, and especially with more than one document. It will not scan.
I use IR for printing single pages only
with either the BJC-80 or BJC-85.
USB to IRDA adapters work fine, and are less expensive $5-6
PCMCIA to Parallel adapters, $20-25.
I have tested and used several PCMCIA adapters from different manufacturers,
and they all work perfectly as a hot-pluggable, instant LPT and/or Legacy
Serial port for my laptops.
After installing the PC Card driver, check Device Manager for the LPT port
Install the printer manually from the list of printers, and select the
proper LPT port.
Most laptops have two PCMCIA slots. If you change slots, the
adapter card driver may reinstall, and assign the next available LPT port,
To scan with the BJC-80, you must have an LPT port.
The PC Card adapter also allows the use of the IS-12 scanner cartridge
within XP or Vista.
Within Vista, set the Canon ISScan software to run in
Windows 98 compatibility mode, to allow use of the TWAIN driver.
