Hi, I use lpr to print. I did a test with opening the original src.png image in GIMP and then having GIMP saving it to a Postscript .ps file and then printing it using lpr. The result was the same (bad results) as if I printed it with IV and Mozilla using X Print. So do you think that it tells us anything?
I'm really not sure how GIMP's print plugin calls lpr and that some how it is giving it more information or something. I'm not sure how to enable the PCL feature in X Print can you tell me how? thanks! -Tara On 2006.10.21 04:04 Drew Parsons wrote: > The middle one displaying gv, is that viewing the Xprint output > postscript file on screen?
