photosmart 7760 driver on PC running RH 7.1

[Allan Adler]

I want to attach a HP PhotoSmart 7760 Photo Printer to a PC running
Red Hat 7.1 Linux. I once connected a Canon Bubble Jet printer to the
PC using printtool and was able to print something out on it. The
printer driver is postscript (i.e. I have ghostscript installed).
Since this printtool is older than the printer, it doesn't know about
it. I don't want to upgrade at the moment. I just want to find whatever
file or information printtool needs to know about the PhotoSmart 7760
and place it where printtool can find it.

As far as finding the printer driver goes, I've went to www.linuxprinting.org
and eventually found a file named

HP-PhotoSmart_7760-hpijs.ppd

and downloaded it. I am not sure whether this is the file I actually need.
If so, how do I make printtool aware of it?

While looking at the linuxprinting site, I saw pointers to a website for
CUPS, which seems to know something about ppd files, but the documentation
for CUPS says that installing it will destroy the existing printing system
on my computer, which I don't want to do. So, I'm rather confused by all this.

On RH 9.1, I got the printer to work by telling printtool that it
was a Photosmart 7550. On RH 7.1, the closest is a Photosmart 1100.
There are no objections from printtool when I declare the printer to
be a Photosmart 1100, but lpr doesn't work with it. It just adds the
file I'm printing to the print queue and does nothing. I don't know how
different RH 9.1 and RH 7.1 are.
