I have a 3b1 with an Okidata Microline 92 printer interfaced to it thru the RS-232 port. I can dump files to it via lp just fine, but the graphics screen dump (SHIFT - PRINT) doesn't work -- it comes back and says it can't find a suitable printer or something like that. I called the ATT hotline, they said their latest list doesn't show this printer as supported for screen-dump. I *know* this can be done, and I would like to try to do it myself, but I don't know where to start. I am still learning the gritty details of the unix system. Has anybody out there done this ? Does anyone else have a uL92 on the unixPC ? Appreciate any help. Thanks in advance. -- -- Charlie Sefranek c4s@rayssdb.RAY.COM

And I did do this once upon a time. I don't do it any more, because it's a bit of a pain, but it's doable. The UNIX PC will only make screen dumps in raw format for it's printers (The ones AT&T likes to sell). You have to fake the system into believing there's such a printer (and it must be the default printer), but change the interface (/usr/spool/lp/interface, I think) into piping it thru a filter (the hard part) and re-queue to the Okidata. What's hard is that the ATT printers use an 8-bit graphics mode, and the Oki is limited to 7, so you've got to pull the data apart and repackage it. Maybe I can resurrect that source code from somewhere.... -- Kevin O'Gorman ( kevin@kosman ) voice: 805-984-8042 Vital Computer Systems, 5115 Beachcomber, Oxnard, CA 93035

Thanks in advance. > > Charlie Sefranek c4s@rayssdb.RAY.COM Waall, I recently implimented some filters on a Sun which print out a pixrect image on an okidata 192, if you want, I could send it out to you and maybe save you some gruntwork once you know how to get the image to it....

I don't have time to research the rest of the problem, but I DO have a 3b1 and oki 192 available to play with if you can tell me where to get the image.
