Hi, Sammy.  Your new wrapfilter script looks fine.  I double-checked the path
you specified for QUEUEDIR to make sure it was consistent with the "sd="
(spool directory) specified in /etc/printcap, and it is.  The only other
thing I can think of offhand is to make sure the wrapfilter script has
execute permission, because I made that mistake when I was setting up my
print queues the other day.  Say "ls -l /var/spool/lpd/lp", and you should
see something like the following:
-rwxr-xr-x    1 root     root         9479 Nov 29 21:29 filter
-rwxr-xr-x    1 root     root          190 Nov 29 21:29 general.cfg
-rw-r--r--    1 root     root            4 Dec  2 12:54 lock
-rwxr-xr-x    1 root     root          360 Nov 29 21:29 postscript.cfg
-rw-rw-r--    1 root     root           32 Nov 29 21:32 status
-rwxr-xr-x    1 root     root          148 Nov 29 21:29 textonly.cfg
-rwxrwxr-x    1 root     root          132 Nov 29 01:21 wrapfilter

The important thing is that you should see "x"s for filter and wrapfilter.
If not, then issue the command "chmod +x /var/spool/lpd/lp/wrapfilter".

This isn't a bug.  ieee12844_print takes the print job data from standard
input, which is the keyboard when invoked at the command line without any
I/O redirection.  Try typing a line or two of text, then press control-D
(which indicates end of file).  It should exit, and the text should print,
although it may be stair-stepped.

I'm glad it works for you now.

What resolution (i.e. dots per inch) are you scanning at?  The higher the
resolution, the more data that needs to be transferred.  Also, color scans
have 24 times as much data as lineart, and 3 times as much data as greyscale.
When there's a lot of data to be transferred, sometimes the I/O becomes the
bottleneck, and the scanner has to stop and wait for buffered data (which it
has already scanned) to be transferred before it can scan any more.  If it's
too slow for you, then try scanning at a lower resolution.  Definitely don't
scan at the maximum resolution (I forget what that is for the 1150).

Sorry about the delay in getting back to you.  As I said above, it looks OK.
In addition to double-checking that wrapfilter has execute permission, it
also might be a good idea to change the "Printer Device" (i.e. port) from
/dev/lp0 to /dev/null, and to make sure the "lp" kernel module isn't loaded.
Type "lsmod" to find out, and type "rmmod lp" if it is loaded.  These two
steps will eliminate the possibility that lp (the Linux standard parallel
port driver) is interfering with the hpoj parallel port driver.

I hope this helps.  If it's still not working even after trying these things,
it would help me help you if you could give more details about exactly what
is going wrong.  For example, exactly what happens when you print something,
either via "lpr" or by sending an ASCII or PostScript test page from
printtool?  Do you see any error messages at all?  Does lpd send you an
error message warning you that the document failed to print (which is what
happened to me when I had forgotten about execute permission for wrapfilter)?
When you run "lpq", does it show any pending jobs?  Are there any spool files
sitting around in /var/spool/lpd/lp (the filenames would probably start with
"df" or "cf")?
