Cups print file

I need a "printer" that just builds a never ending stream. I built the dummy "backend device" which just doesn't seem to work for me. Best I can seem to get is every time I print It DOES get appended to my tmp file. The Word "file:" seems to work even though I have no backend script called "file" works with the overwrite behavior. If I supply a nonexistant backend name like "gibberish" checking the status of the printer tells me that the backend does not exist.

When I change it to my custom backend Printing to it produces nothing. Thanks for the feedback. Sat Oct 31 boborama I changed my backend to append an echo of "hello world" and that worked fine.

It would seem then that the backend is indeed executing Maybe I need to grab the parameters and cat with append what appears to be the spool job path. Don't get me wrong your article has saved me a ton of time pouring over and deciphering a CUPS manual for what ought to be a simple thing to do.

Many thanks. Sat Oct 31 TonyLawrence Huh? This is not a backend script. This is a socket printer with a background script listening at the port. Printer Friendly Version. Show 7 more comments. Sign up or log in Sign up using Google. Sign up using Facebook. Sign up using Email and Password.

If a second banner file is specified, it is printed after the files in the job. The available banner pages depend on the local system configuration; CUPS includes the following banner files:. Higher priority jobs are printed before lower priority jobs, however submitting a new job with a high priority will not interrupt an already printing job.

Normal order prints page 1 first, page 2 second, and so forth. Reverse order prints page 1 last. As shown above, the pages value can be a single page, a range of pages, or a collection of page numbers and ranges separated by commas. The pages will always be printed in ascending order, regardless of the order of the pages in the page-ranges option.

The default is to print all pages. CUPS recognizes many types of images files as well as PDF, PostScript, and text files, so you can print those files directly rather than through an application. If you have an application that generates output specifically for your printer then you need to use the "-o raw" or "-l" options:.
