Remove garbage lines on print out header

[tom quach_1]

Dear all,


I'm using HPUX 11.11 with Panasonic dot matrix printer model KX-P3196

installed as dumbplot printer using jetdirect.

on the print out, it always has 4 lines below on its header.

12345X@PJL EOJ
12345x@PJL USTATUSOFF
@PJL INFO STATUS
@PJL USTAUS DEVICE-ON

does someone know how to remove these lines from the print out. i did switches from "with CR to without CR on the dumbplot and it worked before, but with these Panasonic, it did not work anymore.
Attached a print out report so you can see the the error.
Please help!
Thanks,
Tom

Those are Printer Job Language statements embedded in either the interface files or possibly in the application's data stream.

Cd to /var/spool/lp/interface and edit "myfile" where "myfile" corresponds to the queue name. Those statements should be in that file (or in a file of the same name in the model.orig directory just below /var/spool/lp/interface). Look for those statements and comment them out.

If they are in the applications data stream then the application needs to be changed or a filter (awk, Perk, sed, ...) added to the lp interface file to get rid of that stuff.

The problem is with the hpnp.model parent script. It looks at a variable called DEVTYPE which is defined somewhere outside the script. The simplest way to remove the code is to change the printer's script in /etc/lp/interface. There is a line that runs the network program hpnpf. Just remove the variable $ONUSTATUS like this:

HPNPFOPT="-j $job+$user $TEOJ $TOJMON $ONUSTATUS $xPORT -x $PERIPH $HPNPFLOG $topazopt"
to
HPNPFOPT="-j $job+$user $TEOJ $TOJMON $xPORT -x $PERIPH $HPNPFLOG $topazopt"

That will prevent the PJL stuff.
