Background:
There was a good NG article recently about Epson printers.
Basically, their cartridges now "lock out" refilling and generic
replacement.
Worse, if one uses the printer a lot, the printer itself ceases to
function: only so many cartridges and it is useless (unless one is
willing to spend a lot of money to "fix" what is not broken - just reset
a counter).
And there is *nothing* by Epson anywhere to let un-suspecting buyers
get even a hint of this crap.
Questions:
What is the story concerning HP printers in general?
Can one re-fill as one sees fit?
Can one use generics as one sees fit?
Can one use hundreds of cartridges until the printer *really* wears out?
Finally, what about cartridges for the HP PSC 1400 (HP 21 and HP 22)?
I've got a super-cheap ($89 at Sam's Club) HP PSC 1200, and there
are two files in c:\ that apparently get updated at every print. One
is hpfr3425.log, 251k, that gets added to with each print - has
filename and some binary data. The other is hpfr3420.xml and currently
has this content:
<?xml version="1.0" encoding="UTF-8" ?>
<Usage_Data_Summary>
<Product_Family>hp psc 1200 series</Product_Family>

<Total_Page_Count>1180</Total_Page_Count>
<K_Dot_Count>9389578</K_Dot_Count>
<C_Dot_Count>2825426</C_Dot_Count>
<M_Dot_Count>2324699</M_Dot_Count>

<K2_Dot_Count>0</K2_Dot_Count>

<M2_Dot_Count>0</M2_Dot_Count>
<Total_Drop_Volumn>743485</Total_Drop_Volumn>
</Printer>
</Usage_Data_Summary>
For all I know, the software could easily send this data to HP
and/or use it to eventually say "Sorry, your printer[/scanner/copier]
has reached the end of its design lifetime. Please toss it and go buy
a new HP printer." But I really don't know what, if anything, is done
with this data, and I'm loathe to edit up the numbers to find out.
