In my current job place, I write an *.ppd files for our laserbeam B/W printers, which can emulate PCL5e or HPGL/2 languages. In my case, I want to use rastertopclx filter. I'm trying to understand the model describing via .ppd-file, and many other things, but I understand it's not easy. Now, however, some results there, but would like to ask knowledgeable people about one thing: is it possible to make the description of the printer in the .ppd-file so that rastertopclx sending job in grayscale? This is necessary because if I do a grayscale depth supported by the printer equal to 1 bit, then ghostscript when creating a raster file uses too coarse dithering. If I make a grayscale depth of 8 bits, then rastertopclx uses, it seems to me, error-diffusion dithering, it looks messy. Meanwhile, if I send the job to the printer using the PostScript, then the printer itself uses more elegant dithering. So, I think, if I can send the job through rastertopclx in grayscale, the printer will use a more elegant dithering. Am I right? If it possible, please give me examples of parameters. Thank you.
