HP LJ1000 USB Printer wierdness

I have fighted against the issue that LJ1000 can’t work correctly with FreeBSD however I have failed.

I got “ulpt0: Input/Output Error” when doing cat foo > /dev/ulpt0.

Of course, cups and friends won’t run with this state.

This problem exists in FreeBSD 5.3-RC, 4.10-STABLE. However, interestingly Windows works correctly.

So, why??

这个打印机不是号称只能在 windows 下使用吗?我们这里也有一个,我叫它垃圾 1000 系列,嘿嘿。
好像曾经见过一篇文章写怎么在 linux 下使用这个打印机,记得是在海微的 blog 上面。

Because our USB stack sucks.

Unfortunately there are no Firewire printers, so you have to use expensive network printers or slow Parallel port printers.

Input/output error seems to be gone with

#define ULPT_BSIZE 64

But after firmware upload it now says:

ulpt0: offline
