[wplug-bsd] FreeBSD 4.9-RELEASE Printer Issues

[Poyner, Brandon]

It certainly sounds more and more like a problem with USB.  You might
want to try slowing down the stream of data going into the printer,
perhaps the printer buffer wigs out when it fills up completely?
(doubtful but I'm just grasping at straws).  You could use this perl
script as a pipe to stream ~4K/sec into the redirect to /dev/ulpt0.  

#!/usr/bin/perl -w

use strict;

my $buf;

while(read(STDIN, $buf, 4096)) {
        print STDOUT "$buf";
        sleep(1);
}

The command issued by apsfilter during setup for a test page is:

apsfilter tries something to that affect, but I gave it a shot to be 
sure. Unfortunately, I was not successful.

The results were almost identical, but it was able to print more on the 
page (perhaps because it was text). I almost wonder if it reaches a 
certain amount of input data, then gives up... especially since it is 
consistent in where it cuts-off.

Even using the sample "hpif" filter that comes with the hpijs driver 
(very similar to the gs command from apsfilter), it produces the error 
(though ASCII text prints properly).
