printing - adding form feed

Karen Bennett — Sun, 15 Oct 2000 23:48:01 GMT

I have installed a dot-matrix printer on a JetDirect EX. How can I send a form feed after each report so that the users can more easily tear off their report?

If this is a "standard" printer, a CTRL-L or an ascii code 12 appended to each report will instruct the printer to send a form feed.

you can add the following command in /etc/lp/interface/printer_name

echo "^L" >> /tmp/$printer.$$
mv /tmp/$printer.$$ $1

This commands should be added before the rlp occurs.

Hi,

if you have setup the printer queue with jetadmin then there is a script at /etc/lp/interface/model.orig/
Edit this file and look for a line that contains:
cat $file 2> ....

Insert after this line:
echo "\014\c"

Regards

what's control-L? What's 014? Control-L is the key sequence to run a form feed. This is ascii value 12 in decimal, C in hex, and 14 in octal. The character tells a printer to spit out a page.

Yes, both of them do the same thing ie it gives the printer the FF signal so that the page skips to the TOP OF FORM . So in case you want an empty page after the print out you will have to give the command twice , since one will take you to the top of the next page , and then the second command will take to the next page.

You can test the command by dumping these escape characters on the parallel port device to see the results.

On Unix system, when you create a printer, one file is created under "/usr/spool/lp/interface/".
This file can be used to add every printout a form feed using the command echo "014c"; the same command can be sent directly from your own application for each report.
Hoping to solve your problem....
