I have an older HP855 printer.  I would occasionally get the
'cartridge not installed properly' message also.   On my printer, I
have an HP utility that performs alignment of the two cartridges
when I change one.  That usually kills the message.
The printer speed may be related to the spooling to the printer from
the pc. Check your start/settings/printers/   highlight your HP845,
then right click, and select properties.  You should see a few tabs
- select details, look at the bottom for spool settings.  You want
printer to start printing after 1st page spools, not the last.  My
4-5 year old 855 does about 8 ppm in black text with that setting.
