[lug] Serial printer connection questions

[Chip Atkinson]

It probably doesn't.  I think it has 2M memory.  Maybe a whopping 4M.
I have tried sending PS level 1 files but that doesn't seem to make much
difference in the printer losing track of things.

The weird thing is that it worked great on the mac (which is long gone, so
I can't go back to make it a print server).  I never had this problem in
those days.
