It's the same for the HP LaserJet 4L (unable to print Test A4 Postscript)

This is fixed in an upcomming errata. In the meantime, you can pull the packages
from:

http://people.redhat.com/crutcher/printing/*.i386.rpm

and it will fix it, though they are not signed.

I've got a HP LaserJet 6L. In RedHat 7.1 I used printtool as I could not use
printconf without getting reams of paper with just a single line of unreadable text.

I've only just had the time to apply the updates listed in the "Comprehensive
Printing Update" but still cannot get any satisfactory results.

Using the ljet4 driver causes the processing light on the printer to flash for a
few seconds and then go out, the lpd queue is cleared but nothing is printed.

I tried the ljet5gray driver and that now partly works. When printing the A4
postscript test page, there is a 3 inch gap in the print-out half way through
the RedHat image, the printout then continues up to the line "Here are some
other colors; they" then nothing else is printed on the page. The queue is
cleared after print-out.

I also tried the Omni driver, however all I get is just page after page of a
single line of unreadable text, just as I did before I applied the updates.

I really would like to switch to foomatic as it works with another printer which
I own, however I am having to use an additional linux box which has been
configured with printtool if I want to print out anything on my LaserJet 6L.

Any help is gratefully appreciated!
