Hi there, oldtimer :-) That is more experience than I have, so I can't

Sadly, not easily. So this is just background info for you: The
standard printing system on linux and MacOSX is called CUPS, and is
developed (after being bought) by Apple. There are some ports to
Windows, but not recent or updated regularly.
The open source inkjet drivers for Epson and Canon are contained in a
project known as gutenprint. I am currently maintaining and developing
the Canon part of this. Effectively, without any input from Canon, I
work by parsing printjobs captured under Windows XP, using all
possible combinations of print media, quality setting, color/mono,
duplex, media tray and borderless. As needed, new functionality is
incorporated, and as time permits, lacking functionality added and
thereby automatically backported to all existing supported printers.
So if you have an old printer that is no longer supported under
Windows 7, for example, it will forever be supported in open source.
A strength of CUPS is that is manages printers over a network, and has
great administration facilities. So it is not necessary to have a
driver for a printer on the machine you are printing from, only the
machine where the printer is attached.
A downside of CUPS is that it is not interactive: that is, options are
not interactive like in Windows---all options are always available,
and the driver has to do the work of prioritizing and selecting which
combinations are legitimate or not, if the user made incompatible
(from the printer firmware perspective) selections. This is usually
not a problem, but can be, in such complex devices as, for example,
ALPS printers with multiple operating modes.
In such situtations, multiple PPDs, one for each distinct operating
mode, are the best idea, and a new printer is set up for each mode
(the same could be done if you have some fixed requirements, such as
monochrome printing 2-pages per sheet in draft mode; compared to color
printing at standard quality 1-page per sheet).
Enough of that :-)

OK, that is probably mechanical-related, not much the driver can do
about that I surmise.

Windows spooling has problems sometimes. Could also be memory issues
on the spool or in the application creating the printjob. It isn't
really fair to blame the printer for this, but you could blame the
driver if it doesn't send the job properly (if indeed that is the
cause of the problem.

Understandable.

No worries! If you ever decide to use MacOSX or linux, you can rest
assured there is plenty of printer support!
