I think your scanner uses the same ASIC that 600P/610P use, and is different
from the one currently supported in the umax_pp backend. Maybe older 1220P use one,
and newer another one.
When I do a 'modprobe lp', with both scanner and daisy-chaine printer
powered on, I get the following:
0x378: FIFO is 16 bytes
0x378: writeIntrThreshold is 16
0x378: readIntrThreshold is 16
0x378: PWord is 8 bits
0x378: Interrupts are ISA-Pulses
0x378: ECP port cfgA=0x10 cfgB=0x4b
0x378: ECP settings irq=7 dma=3
parport0: PC-style at 0x378 (0x778), irq 7, dma 3 [PCSPP,TRISTATE,COMPAT,EPP,ECP,DMA]
parport0: Found 4 daisy-chained devices
parport0: faking semi-colon
parport0 probe: warning, class 'IMAGE' not understood.
parport0 (addr 0): Unknown device, UMAX Astra 1220P
parport0 (addr 1): Printer, EPSON Stylus COLOR 440
parport0 (addr 2): Printer, EPSON Stylus COLOR 440
parport0 (addr 3): Printer, EPSON Stylus COLOR 440
parport0: Printer, EPSON Stylus COLOR 440
lp0: using parport0 (interrupt-driven).
What does your log report in this case ? Note in this case, and for
any UMAX 1220P reports I had, 4 daisy-chained devices are allways reported.

Your scanner is detected as a 610P, and support for this model isn't
complete. Only detection is working. So it fails where support stops....
