Correct, usblp was blacklisted after CUPS installation, I've rebooted several 
times. Even more, my kernel doesn't have usblp module, both «sudo modprobe -l 
| grep usblp» and «lsmod | grep usblp» show nothing. dmesg output is the same:

[  306.582323] usb 5-1: new full speed USB device using uhci_hcd and address 2
[  306.740409] usb 5-1: configuration #1 chosen from 1 choice
[  306.747338] usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid 
0x04E8 pid 0x325B
[  332.238856] usb 5-1: usbfs: interface 0 claimed by usblp while 'usb' sets 
config #1

Also, I've updated initramfs and rebooted again. It didn't help.

Also, I remember one small detail — after first CUPS upgrade in unstable 
everything worked well. But CUPS 1.4.0-4 asked me to rewrite its config, and I 
agreed. After this (I think that after this, but not sure) CUPS stopped 
working.
