HowTo setup Lexmark X73 scanner/printer + MEPIS 3.3

I hope this is useful to anyone else using the Lexmark X73 printer/scanner. For the printer I used the KDE Add Printer Wizard and selected the following driver: "LEXMARK Z42 - CUPS + Gimp-Print V4.2.7". This printer works well. For the scanner see the following:

Lexmark X73 scanner set up notes:
=================================
1. With the X73 plugged in and turned on opening Kooka returned the following:
Problem: No Scanner was found
Your system does not provide a SANE (Scanner Access Now Easy) installation, which is required by the KDE scan support. Please install and configure SANE correctly on your system. http://www.sane-project.org/.

2. Scanner was found using "sane-find-scanner" and "scanimage -L":
root@1[~]# sane-find-scanner
found USB scanner (vendor=0x043d, product=0x002d) at libusb:001:003
root@1[~]# scanimage -L
device `gt68xx:libusb:001:003' is a Lexmark X73 flatbed scanner

3. xscanimage returned a useful error message:
guest@1[~]$ xscanimage
[gt68xx] Couldn't open firmware file (neither `/usr/share/sane/gt68xx/OSLO3071b2.usb' nor `/usr/share/sane/gt68xx/oslo3071b2.usb'): No such file or directory

4. This is a dual boot box (Win98 + Mepis 3.3) and the Lexmark X73 software was installed on the windows partition. The file was found on the Windows partition and copied to the location and name specified in the error message. Note the case change in the extention to match the error message.

root@1[~]# cp /mnt/hdc1/windows/OSLO3071b2.USB OSLO3071b2.usb

Note: I searched the Lexmark X73 software two CD set provided with the product and did not find this file. Perhaps OSLO3071b2.USB is created/unpacked during the Lexmark X73 driver Windows install process.

5. Scanner now operates normally when Kooka is started.
Note man page is available for "sane-gt68xx" driver.

Enjoy,
