[cups-devel] Image Control on OKIDATA 490

[Helge Blischke]

I’d use the printer’s IBM ProPrinter emulation (as this PDL is fairly documented) and write a continuous stream driver
for image data on the bases of Ghostscript’s makeimagedevice, generating the proprietor stream by PostScript programming
and using page control commands only at the beginning and end of the print job.

I’m running a node app (with node-printer) on the computer side to take care of the logic. I’ve got the basics working, but I’m having trouble controlling the size and placement of images.

I modified an image filter to remove the lines regarding blank space, but I’m having trouble compiling (can’t find ijs package?), and I don’t even know if that’s the right solution. I also have tried to send different options to lp, such as position=top and natural-scaling=25, but it seems to have no effect. I am running a Mac on El Cap, if it makes any difference.
