One good news and one bad news about pogoplug and cups

I've made some progress setting up cups on pogoplug. It's not working yet, but I feel like it's sooooo close. 

I first tried cups in optware packages, but somehow all binaries in the package gave me segfault.

So I downloaded cups-1.3.10 source, and compiled/installed it myself (after installing optware development tools - gcc, make, etc). Then I realized that the kernel has usblp driver, but somehow /dev/usblp0 isn't there (even when the printer is plugged in, and dmesg shows kernel recognizing it as a usb printer). So I created a device myself "mknod /dev/usblp0 c 180 0" - the major number and the minor number was taken from:

bash-3.2# cat /sys/bus/usb/devices/1-1.3/1-1.3\:1.0/usb\:lp0/dev

180:0

bash-3.2#

After this, cups backend recognizes the printer:

bash-3.2# /opt/lib/cups/backend/usb

direct usb://Samsung/ML-1740 "Samsung ML-1740" "Samsung ML-1740 USB #1" "MFG:Samsung;CMD:GDI;MDL:ML-1740;CLS:PRINTER;MODE:GDI;STATUS:IDLE;CODE:10001;"

bash-3.2#

I've installed splix as well. However, I've never setup cups manually before, and I was lost in setting up cups. After many trials and errors, I still don't have successful cups setup - I've tried two different paths, one setting up the printer as "raw", and have my windows box to install the printer driver on its side. And the other was to use splix and have windows recognize it as generic postscript printer. However, I couldn't get either of them working - generic postscript setup didn't work because cups was giving client-error-document-format-not-supported error with a message "unsupported format: application/postscript" or something like that. I don't understand why this is happening, as seemingly correct .ppd file is installed and configured for the printer... Then the raw mode somehow never worked either and I couldn't figure out why, and by the time I got to that stage, it was waaaay to late so had to sleep :/

If you're a cups hacker who can give some advice in this sitation, it would be awesome. It's so close to pogoplug nirvana....
