When I submit a certain file containing non-textual data for printing on a dot matrix printer, some operating system entity apparently filters out some of the bytes. How can I get this file to /dev/lp0? It prints just fine from dos (:-) Somebody locally suggested making an ioctl call, but my experience with this is null, & I haven't found any obvious manual references (that I recognize) to this. I do have the development system, in case an alternate printing program is required. Thanks to all who consider this problem. -- My .signature is awaiting apropriate display technology

I use the print spooler (for which the setup seems to be one of the more challenging aspects in Unix) and pass it nroff output which includes various control codes. I would guess that if you use something like 'cat >/dev/lp0' that cat might strip out control codes.

Wrong. The reason for the failing is a bug in the original parallel driver.
Get the fix unx-162 form SCO support and all is fine.

This is just a guess, but would you be using the printer on the parallel port? If you are and you dont have SCO's SLS (Support Level Supplemnt (Patch)) called unx162, you may get the 8th bit stripped off. I am not sure but I think you have to call SCO to get this patch. -- David Arko, (darko@hpspcoi.hp.com)
