Perhaps someone who knows more about your printer could make sense out of
that log. It doesn't mean much to me.
However it is apparent that a fair amount of information is going back and
forth. The usblp driver provides a path for this information but doesn't
generate any of it. That's up to a user program.
You can write a program to do a soft reset. Here's what it needs (taken
from the usblp.c source code):
#include <sys/ioctl.h>
#include <asm/ioctl.h>
#define IOCNR_SOFT_RESET 7
#define LPIOC_SOFT_RESET _IOC(_IOC_NONE, 'P', IOCNR_SOFT_RESET, 0)
...
fd = open("/dev/usblp", O_RDWR);
ioctl(fd, LPIOC_SOFT_RESET, 0);
