Re: Printers Revisited

Hello All:

Actually I'm printer agnostic. I would like to add two little bits of
information to the discussion that might be relevant.

    Power saving settings are adjustable on most laser printer. There is an
internal clock that kicks in after each print job is completed and if the
time between jobs exceeds the power saving settings, the heaters/fusers shut
off. The fusers actually melt the toner into the paper. Otherwise, the
toner just falls off. It is possible to change the economy or power saving
settings so the printers are 'hot' effectively all the time.

    I have not found any HP or Brother printers that don't send paper
through a U shaped or 180 degree path even if you use the sheet feeder.
Epson printers seem to put the paper through a 45 degree bend but very few
manufacturers discuss paper paths in their literature. It seems to be
necessary to wrap the paper around something to properly present it to the
printing apparatus. Even large format plotters do this. Although I think
someone may have already mentioned it, laser printer output usually comes
out face down basically to preserve page order. You have to tell ink jet
printers to print from the last page first to have them preserve page order.
BTW, for a different application, I'm looking for a more or less flat bed
printer that runs paper almost straight through a printer. My HP 932C Desk
Jet has problems handling card stock. If anyone has information on that,
please contact me privately.

Thanks, Ed Kennedy
