Help needed with printer under ix/386

[fritz zaucker]

Hi,
another questions from me. I have a HP LaserJet series II
connected to the parallel port of my 386 running ix/386.
I got it running (thanks for filters I got after my last
request) and it works.
If I send a file to lp containing about 40 kBytes of processed
TeX code it lasts about half an hour or longer until the 4 pages
are out of the printer. If I do the same under MS-DOS it's
about 55 seconds.
Does anybody have an idea about that?

Thanks
Fritz
