Cat seems to prefix lp output with a 00.

[Concerned3 Netizen]

I'm trying to send a file to a barcode printer and it's ignoring my data stream because it's prefixed with an ascii 00.

The first character in the data is not 00.

The command i'm using is cat /tmp/label |lp -dprintwiz

Anyone know what might be the problem and how I can get around it.

I doubt its cat that is doing it. More likely, the print queue virtual
printer that you are using has a virtual printer formatter that is doing
something. To confirm:

cat /tmp/label | od -xc

or just try your lp command without cat:

lp -dqname /tmp/label

Try this:

qprt -Pqname -j! /tmp/label

The -j! disables the virtual printer initialization of the queue prior to
the job.

Best regards,
