HP Inkjet Dev Kit 27949

I need help with the HP inkjet development kit. I'm trying to print from
VB6, and here are the steps I've taken:
- the FTDI drivers are installed - the P61497 board appears as Com9,
whether the On-> switch is on or off on the Parallax board.
- I installed the inkjet cartridge and inserted the ribbon cable into
the Parallax card. The instruction manual doesn't contacts up or
down, so I've tried both ways. No connections to the 4-pin header.
- I added +5 to the 3-pin header - power LED glows brightly with
switch on.
- I wrote a VB6 program with an MSCOMM1 and a button with the
following code underneath its click event:
MSComm1.CommPort = 9
MSComm1.Settings = "9600,n,8,1"
MSComm1.PortOpen = True
MSComm1.Output = Chr$(27)
MSComm1.Output = Chr$(2)
MSComm1.Output = "test"
MSComm1.Output = Chr$(3)
Nothing happens at the printer head. No flashing lights on the 1-12
LED indicators.
Any ideas how to print from the USB connection?

Running the simple_print.bs2, I get a vertical row of dots (like an "I") every
half-sec or so with my ribbon one way, and a single dot plugged in the other way
(notes don't see which way to plug, though the book suggest it oughta work
either way). I watched Matt Gilliland's video and sped up/slowed my the printer
with my hand - *maybe* a get a little spreading of the dots, but it's definitely
not printing.
I also ran the character downloader thinking maybe it didn't ship ready to go.
Ran fine, but no improvement. So, what I get is a slow, periodic "I", that continues
for as long as you want to watch (and there's no loop in that sample program...?)
None of the 12 LED indicators flash either - ? I tried all variations on cycling
the power per the notes.
Any idea what I'm doing wrong?
Any help is much appreciated!
Thanks, Gregg
