[Bug 35638] Re: Brother Hl-1050 and HL-1430 are not detected properly over USB

[Stanley Sokolow]

Have you looked into the hunch I posted quite a while ago?  The cycling 
timing may be due to the driver looking at the wrong status bit.   If it 
is looking at a bit which goes on & off to indicate status of the fuser 
heater temperature, it would behave like it does -- random on and off 
intervals as the fuser heater goes on and off to maintain temperature of 
the roller.   Maybe the driver looks at the fuser status, not the 
printer-ready-to-receive-data status bit.   When I use the parallel 
port, the printer works fine.  Parallel port doesn't have a fuser status 
bit to confuse a driver, only a printer status bit.  The problem is not 
in the printer, but rather in a driver that looks at the wrong status, I 
think.  Perhaps Brother support can give you a document that details the 
status information which the printer reports.
