Description of problem:
After updating one of my computers from cups-1.3.5-3 to cups-1.3.6-2, the
Samsung ML-1210 printer that's attached to it by a parallel port stopped
working.  It does nothing at all when you send it a print job.

Going through system-config-printer and hitting "print test page" brings up a
window that say s"Submitted  Test page submitted as job 79" (the number
increments every time) but nothing prints and the busy light on the printer
never starts flashing so it apparently receives no data.  The button changes
from "print test page" to "Cancel tests" when I close the "submitted" window, so
I click that, and that's all there is to that.  The "Printer state" line on the
screen never changes from "idle".

Going through http://localhost:631 and printing a test page from there says
that the test page was sent, but when I check the list of jobs there are "no
jobs" and the printer never does anything at all there either.

I have removed and reinstalled the ML-1210 printer several times through
system-config-printer but nothing changes.  I have switched the printer off and
back on, and even rebooted the whole computer a couple of times.

Here is what I get in /var/log/cups/error.log when I click the "print test
page" button in system-config-printer:

Further, if I try to print a document of any length to the
locally-installed CUPS-PDF I get a 760 byte file that's apparently a single
blank page.  I just tried printing a 57-page document to cups-pdf on that
machine and got the same 760 byte pdf file that I get when I print a single
sheet that says "This is a test."

I can print from that computer to a shared HP printer (USB-connected) on a
different computer.  I can also print to that USB-connected printer locally from
the computer that it's attached to.  It is using the same version of cups.

Version-Release number of selected component (if applicable):
cups-1.3.6-2.fc8


How reproducible:
every time

Steps to Reproduce:
1. Print from any application to cups-pdf
or
1. Print to locally connected parallel Samsung ML-1210 printer
  
Actual results:
760 byte pdf file that's a blank page
or
Nothing happens at all.

Expected results:
Larger pdf file containing the text printed
or
Page printed on the Samsung ML-1210
