HP Laserjet 1012 solution (worked for me, anyway)

[Guest]

This eliminated the "unsupported personality" errors and seems to have fully
enabled the printer under Vista...I think it would work for any in the HP
1010 series.

Use the Vista Laserjet 1015 driver. One the driver is installed, open the
properties for your printer. Under the "Advanced" tab, press the Print
Processor button.

Select the WinPrint processor and Default data type of "Raw".

Once I did that, I was able to print multiple copies and print other
documents I was having problems with.

I have an HP Laserjet 1012 myself. I know that you can use the XP driver and
very painfully install it to have full support, or you can simply use the HP
Laserjet 1015 driver for full support as well.

I too have the 1015 driver and the Print Processor set to "Raw" for my 1012
and it still does not work. The only work around I have been able to find is
to unplug the power from the printer and then power back on... It will work
for me for a few pages and then I have to rinse/repeat.
