[comp.sys.apple] Imagewriter and //e

jstraigl@uokmax.ecn.uoknor.edu (Jeffrey S Traigle) (12/01/89)

This is a problem I have since I got my //e and Imagewriter
about 7 years ago.  For the first year or two I hardly ever
used my printer so it didn't bother me too much.  Over the
course of the last few years it has really gotten on my
nerves and would apreciate some help with it.

Now since you're probably wondering what this problem is now
I'll tell you.

Sometimes (read 98% of the time) when I try to print something
all the printer does is spit out some garbage.  The only way I
have been able to print anything is to turn the computer off
and on until the printer decides it wants to cooperate.

Also, lately (within the last year), if I am printing any long
documents, I hold my breath hoping that it will get through the
entire thing without any problems.  It seems that sometimes the
printer decides that it wants to print in compressed form over
some short string of characters.  Once it goes back to standard
it continues normally, except sometimes it starts printing as
if the middle of the page were the left margin and things really
get screwed up.

Does anyone have any idea what has been and is the trouble with
this thing?  Thanks in advance.

You say you purchased your IIe system in 1982 (seven years ago).  I didn't know
they were making Imagewriters back then.  I thought the Imagewriter came out in
1984 or so as THE printer for the Macintosh.  (Never mind that it's also a 
great printer for the II!)

I'm no hardware expert, but it sounds like you have some sort of glitch.  You
might try feeling the printer to see how warm it gets.  Is it running hot?
Heat affects RAM in a negative way, so excessive heat might change a bit here
and there in the print buffer.  These glitches happen to manifest themselves as
printer control codes.

Another possibility is that one or more chips might just be bad.  A bad ROM 
could change print styles as it sees fit.  Who knows, maybe even the driver
circuits for the print mechanism are shot.

Just some ideas.
