# Lexmark E260 and E360 Postscript takes about 30 seconds to print a page.
# Expanding the memory to max does not help. Moving to the MS810 drops the time to 15 seconds.
# PCL5 and PCL6 print at full speed with standard memory.
# Postscript is the only driver Foomatic provides.
# PCL5 prints at 300dpi. PCL6 prints at 1200dpi.
# Here we enable PXLMONO

# Chances are the E460 has the same problem but I don't have one to test.
# Let me know if it should be added.

# https://bugs.linuxfoundation.org/show_bug.cgi?id=1420 Add pxlmono to Lexmark E260 E360
