I made a typo on the original post, it is a Dimension 4550.
On this system I have a USB HP Scanjet 3500C, USB mouse, usb memory card
reader, and have connected a digital camera all with no issue.

The original printer I have was a parallel printer and then wanted to add a
HP Laserjet but
had no success and ended up installing on another system and then accessed
it through
our home network. At this time I thought it might be a HP driver issue.

Now I purchased the EPSON Stylus PHOTO R200 mainly for the feature of CD/DVD
printing capability. Since this printer will not install on this Dimension
4550 I suspect
something wrong on this Dell.

Regarding the HP LaserJet I had successfully installed it on our Dell Laptop
and another Dimension
4550. The only real difference I could find between the two Dimension
systems is the one were
the USB printer installs successfully has bios version A02 while the other
Dimension as a newer
bios, A08. I tried to go back to an older bios but it would not let me.

I tried installing the EPSON on the laptop and it installed with no problems
so I know the printer
is ok and the USB cable is ok.

It appears that the problem is that the printer is not being identified as
what it's full description is,
only as a USB printer and then when it looks for an entry in the inf file it
can't find it.

Thanks,

Paul

More information on the exact symptoms would help. Is it a 4500 or 4550?
You mention both in your two posts.

My Dimension 4550 has:

Epson 1270 inkjet
Samsung ML1710 Laser
Epson 7600 inkjet

All attached via USB. The Epson 7600 is a 24 inch wide rollpaper photo
printer, so it's a pretty big printer and it works fine. The same machine
has a Hauppauge WinTV USB PVR2, a USB Wireless keyboard and mouse, a Seiko
label printer and three USB2 hard drives attached.

So far I have never been able to install either a HP Laserjet or EPSON
Stylus
USB printer on our Dell Dimension 4500.

Anyone have any suggestions.

Thanks
