Line Printer not including Form Feed at end of prints

[Joe Robinson_1]

After changing a line printer from a serial printer to one utilizing a HP Jet Direct (HP EX Plus) device, the printer now won't put a form feed at the end of the print.


I've checked another of my interface files (I used diff to check between the two, with the only differences being the IP address). I'd appreciate any suggestions the wisened wizards (or any other royalty...I'm working on it!) might have.

Thanks,

Hi Joe,

One easy way to do this is to modify the
interface file for your printer.

as an example, we will use printer 'myprinter'

cd /var/spool/lp/interface

There will be an interface file 'myprinter';
edit it and locate a loop which calls hpnpf
and modify it.

The idea is to build a temp file containing a FF and cat the regular file + the temp file to the hpnpf (JetDirect) filter. When done, you remove the temp file. The attached script does just that.

Hi Joe

There is one more way to do it , at the end of the data file to be printed try adding cntrl L which will get translated as form feed when put to the printer interface.You can try just by printing a file containing cntrl+l .

Very important: JetDirect scripts in the interface directory are generic and only handle the LAN process. The 'real' script is located under the interface directory in the model.orig directory. This is the script that controls the printing behavior of the print job.
