I have been reading that an image scanned at 1200 dpi can be printed out
at 300 dpi to obtain a reasonable quality enlargement.

I don't have a dpi selector on my hp deskjet 3420 driver. Is their a
work around for this ?
Thanks.

Some free graphics software (e.g. Photoshop Elements,
distributed with some cameras) has this facility. You
should be able to specify (for any source image)
(1) Printout dimensions in cm. or inches.
(2) Printout dot density.

These are more properly referred to as 1200 and 300ppi in these cases. PPI
being pixels per inch.

Printer dpi is something completely different than image ppi, confusing
called dpi sometimes.

To help get an understanding of these concepts and the differences, I'd
recommend looking at the info found at
