Print to file in Unix

In Microsoft Windows, it is possible to use the "print to file" option when printing. In this case, the binary data, including printer control codes, is written to a file instead of being sent to the printer.

I want to do this in unix (ideally Hewlett-Packard unix), in order to see what control codes are being sent to the printer.

NOTE: I want to see the printer control codes added by the unix printer driver, so simple file redirection (using the ">" character) will not work.

If you know any way to see the printer control codes added by the unix printer driver, this will solve my problem.
Many printers have the feature of hexa-dump mode.
Under this mode, printer will output each byte received to hexa
value, no matter what it is data or control code.
I called it as "printer debug mode" and it is hardware-level
debuging. It works for DOS, Windows, OS2, Unix, ......
The only factor is "You can print data to printer under your OS".
Maybe you should check your printer manual how to setup hexa-dump
mode. If failed, tell us about your printer style.

Not the solution you were looking for? Getting a personalized solution is easy.

There is a second option here, which is to temporarily disable the system spooler.

The result of this on many UNIX systems is that the printer will accept the job, and create the output file, but as the spooler is not running it will maintain a file in the jobs directory.

You could then hd (hexdump) the file to see the codes, or hit it with an editor or ??

Remember to reenable the spooler when done.

Hello Jackie and Cemaylor:

Thank you for your suggestions. I have passed them on to the engineer in the location where the printer is and am waiting for him to report on the results of applying your 2 suggestions.

At that time, I'll grade your answers.

Thank you for yuor help.
