 CUPS filter for thermal printer Zjiang ZJ-58
+
+The linux driver provided on Zjiang site unfortunately doesn't work.
+First, it is 32-bit binary (and so, on x64 system need some x86 libs to be installed).
+Second, it's PPD is not correct - it just doesn't show any advanced settings because of it.
+Finally, raster filter just crashes on any try to run it!
+But even if you run it, you'll see that it's working with printer is not optimal: for example, if it sees a blank line, it will send the blank raster to print (instead of just use 'feeding' command, which is definitely faster!)
+
+This is the solution:
+PPD is fixed and works.
+Filter is provided as src (you can found a list of packages need to be installed in order to build it in the header of source).
+Also, printing of blank lines is optimized.
