 any two lines text file needs 15 minutes to be printed

 does not fix, the problem is as well with lpr and cups local/remote
 
 the only way to get "some more speed" is using b/w and 150 dpi on a HPDJ, a=
 ny=20
 gray or color mode is slow

 doesn't matter what you set in the BIOS or whatever, any gray or colormode =
 on=20
 5.3 is that inacceptable slow
 
 using the exactly same printer and port settings on 5.2.1 or 4.11 brings yo=
 u=20
 back to the expected printing speed
 
 you even can use the exact same clean ports tree and compiling cupsd +=20
 foomatic and 5.3 is slow and 5.2.1 and 4.11 is normal speed
 
 But printing to a remote cups tree from 5.3 is giving the normal performanc=
 e.
