Inkjet Printers using Color Inks while Plotter uses Color Pens
for printing.

Model 1
-------

1. Alternatively Can inkjet printer also can have Pens as a source for printing OR Plotter can also have Color Inks as a source for Printing ?.

Model 2
-------

2. Alternatively Can inkjet printer as well as Plotter can have both Color Inks and Pens as a source for Printing. i.e. An inkjet has both Pens and Inks installed as well as Plotter has both Pens and Inks installed as sources for printing ?.

Can there be any advantages in manufacturing those above two Plotter and Inkjet Printer Models ?.

Awaiting your reply,

Thanks & Regards,

ANSWER: I don't see why not but I am not an expert in this area.  Generally speaking the plotter is a more precise instrument and perhaps the pens donot yield as good results for accurate lines.  But, I don't know the details well.

Suggest you ask of manufacturers of these printing devices such as HP, Canon, etc.

QUESTION: Dear Prof Cleggsan

Thank you.

Can we install Pens along with Ink Cartridges in Inkjet Printers ?.

Could this be beneficial for printing vector as well as raster Graphical
color images ?.

Awaiting your reply,

Thanks & Regards,

Answer
As before, I am not an expert in printing design or engineering.

This is an esoteric field; mostly paved with experimental results and corporate secret know-how.  The ballistics of the ink holding apparatus are effected by its mass (weight) and stability.  The ink dispersion is a fluid dynamics problem involving its viscosity and contact angle with the dispersing agent and the writing materials.  It is all very complicated but highly developed over the years by the few makers of various kinds of printer/plotter makers.  

On the other hand, it is a very robust product category as there are thousands of old printers using the early designs that are still running daily.  In plotters I know that it is common for when a printer pen runs out of ink to stick an office supply pen its place and finish a print even though the color changed or becomes a ball-point pen finish.  So, there is flexibility in pen driven solutions that are not available with ink jet designs.  

So, I don't know the answer to your question but I think it is not an easy one.  Technology aside it is a market driven issue as well for aftermarket supplies of support materials used by the user is a thorny issue.  Also, cost and manufacturing difficulties are quite different between the two ink delivery containers.

Three cheers for wading into a tough area.

Good Luck.
