At least a few others have suggested diagnostics that will help
eliminate/prove causes.

That is a really strange problem. Have you tried your printer on another
computer? (Basic question, I know, but we sometimes forget.)

For example, I tried `CUPS + Gutenprint' for my L7500, and the output
was pretty bad. I tried many other variants, and `Footmatic/hpijs' was
the best (it was apparently the recommended one). How is the printer
connected to the computer? I have no experience with laser printers.

I created a new CUPS printer using the Generic Postscript driver and it
does not appear to produce the problem. Printing a test page from the CUPS
maintenance screen it prints perfectly but in monochrome only.

Printing a spreadsheet using this printer doesn't produce the problem
either but I did select 'Postscript 2' and 'Colour' rather than 'from
driver' and it did print colour.

It does look like the HPLIP driver is causing the problem.

I avoid using HPLIP for our HP laserjet b/w and colour printers. We have
4050, 4100, 42100 and 4600 printers in the office.

Printers like these ones, which have a very good support for PostScript,
have been working without glitches for years using just CUPS and PPD
files. PostScript driver can be slow with some works but delivers the
best printing quaility.

Sure, there is no fancy monitor status displaying the toner levels but
you can always check that in the embedded webserver of the printer or by
printing a status page :-)

I would only use HPLIP for multi-function devices for cartridge cleaning,
printer calibration, fax facilities and so on... but laser printers do
not need all that stuff at all :-P

Unfortunately, that's not possible, as I don't have access to another
computer to try it on.

> connected to the computer? I have no experience with laser printers.

Via USB, as hplip doesn't recognise parallel printers [at least from
Debian repos](0). Barry's is the laser printer, mine's an inkjet.

[0] It is possible to use parallel printers with hplip but, by default,
the ability is off at compile time. I've never pursued the issue the
the Debian maintainer but guess he doesn't enable the feature.

I also want to go direct to HP to use hplip since their way uses a
very unDebian like install method. On top of that, I already install
four packages manually, and don't wish to make that five.

Finally, for me, this is a minor 'nit' as I don't do a great deal of
printing. I can see though, it would be costly for users that make a
lot of use of their printer(s).
