Besides printing, the HP OfficeJet T45 is also capable of scanning and is supported by the hpoj package and sane. I could not get this working however under Centos 4.2 (and this already once stopped working in the past after doing an upgrade on RedHat 8). Sane would not find the scanning device.
I finally found that the one important library that is missing from the hpoj package (hpoj-0.91-9) is libsane-hpoj.so.1.0.
I solved this by compiling hpoj from source, copying the file to /usr/lib/sane and creating two links in the same dir to it: libsane-hpoj.so and libsane-hpoj.so.1 .Not ideal but it works. I take it the file is also missing upstream ?
Now kooka (also) scans perfectly.
The one thing I now still have to solve is that printjobs stay in the queue while the hpoj service is running. I guess I have to define the printer differently because hpoj locks the parallel port. Currently it is using the hpijs driver.
