From Bugzilla Helper: User-Agent: Mozilla/5.0 (compatible; Konqueror/3.4; Linux) KHTML/3.4.0 (like Gecko) Description of problem: it would be great for all users with hp printer if we could add a patch to ghostscript gdevijs to support krgb: http://hpinkjet.sourceforge.net/updates.php#a160 ######## Â Added KRGB support. HPIJS now supports two color spaces RGB and KRGB. KRGB provides image enhanced printing for black text and black line drawings which can not be done with current RGB based raster drivers. KRGB definition: 1. K=1-bit black plane, RGB=24 bit color raster. 2. K-plane will only contain objects that are black text and black line drawings. 3. RGB raster will not contain K-plane objects. 4. K resolution and RGB resolution will be equal. 5. K-plane will be byte aligned. 6. K-plane bit definition; 1=black, 0=white. KRGB requires Ghostscript suppport. Current versions of Ghostscript do not support KRGB. In order to support KRGB, a Ghostscript KRGB patch is included in the HPIJS package. The patch modifies the IJS client in Ghostscript and is free to use under the MIT license. The new IJS client should be backward compatible with existing IJS servers. This means KRGB support is optional. Use the following command in the Ghostscript source directory to apply the KRGB patch, then rebuild Ghostscript. $ patch -p0 < gdevijs-krgb-1.0.patch ############# Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. 2. 3.
