H havn't driver for Color FlatbedScanner11 SCSI Scanner Device 320p

First you would need to make sure you have a parallel port on your computer, because if you don't, you would need to get an adapter of some sort for either a p2p or usb port, whichever you prefer. I'm not sure if you can get a parallel cable from the manufacture, but you could probably find it on eBay. With an older scanner and a newer computer, you can probably just plug it in and it will work, but if you need the software, go here: http://www.nodevice.com/driver/320P/get25293.html

Hope this helps!

along wid the company, there will b a list of such site n driver download links if u search by the model name on a search engine like google..
download them onto a location; if the driver is in a zip format, unzip it,if itz in .exe form, just run it; if done manually it'll ask for the correct driver and location; relocate the path and a .inf file (wat it'll ask for)..
however try this:

but always better to consult system admin/vendor....

hi
here is the driver link for your product AcerScan Prisa 320P
(This driver is for Windows XP)

ftp://12.145.38.159/scanner/drivers/parallel/mirascanv3424p.zip

just download and unzip and install

have a nice day

I'm assuming you need the 320p software since I couldnt find any "Acer 100" scanner. I uploaded the Acer 320p driver here:

Install on Vista and Windows 7 using driver files from a XP installation. Copy the following driver files from XP: umax.inf, layout.inf, sti.inf, scsiscan.sys, sti.dll, umaxscan.dll, umaxud32.dll, umax.pnf (this may be more files than you need, but it works). Edit the umax.inf file to remove all by the 1200s/SCSI related sections (or copy it from below). Perform a manual installation of the 1200s and select the umax.inf installation file that you copied and edited. This worked perfectly. My Umax 1200s is recognized and works great in Windows 7.
