I have encountered in past lives, printers that needed a final form feed, chr$(12) before they would print the buffer. I do not know if that includes the Brother MF stuff, but I have 2 of their HL series laser printers here, and both work well using the driver/wrappers and ppd's suplied by Brother for use with cups and have worked well for several years now. They don't call home, and they Just Work(TM). However a recent nearly 8 hour power outage caused by a 200 yo tree falling off the mountain in an ice forming storm, onto a main circuit coming into town, did disclose that having a standby generator with a 5 or 6 second response time can put the color laser at least, into an unusable state which a printer panel power cycle will not reset. It must have the power cord pulled for long enough to move it to a different pluggin in my system here in the coyotes.den. I did have it straight into the wall, and moved it to a different plug that has a very high rated, 5 kilojoules IIRC, surge arrester behind the plug. And amazingly, that longer powerdown, probably over a minute because the cord was so entangled in the midden heap here (its been collecting for 26 years now :), apparently fixed it. Your trivia factoid re Brother printers for the day ;-) If all else fails, do a prolonged, power cord unplugged, reset.
