[comp.sys.mac] Bidirectional printing on ImageWriterII

drg@wjh12.harvard.edu (Dean R Gallant) (07/29/88)

I'm trying to achieve high-quality output on my (new) ImageWriterII.
Due to an alignment problem, letters are slightly ragged when the 
printer, in "best" mode, prints bidirectionally.  I had thought 
that the IW printed left to right as its default, and switched to 
bidirectional if one held down option-shift-caps lock while
clicking ok in the print dialog box.  Mine, at least, seems _always_ to
print bidirectionally, except occasionally (but--alas!--not repeatably)
just after I cycle the power to the printer.  

Am I missing something obvious?  Is there an easy way to disable
bidirectional printing?  (Finder 6.0, Sys 4.2, IW driver 2.6, Word 3.02)

Thanks for any advice.

 In response to my request for help with an ImageWriterII dot-alignment 
problem, Karl Kornacker forwarded some comments from David Shear's 
documentation of his bitmapped font "Columbia," the gist of which 
were that the two factory preset DIP switches that the manual tells 
you Not To Fool With (SW2-5 and SW2-6) may be worth adjusting.  

 In my case, the factory settings were "closed-closed" and, of the 
four possible permutations--all of which I tried--that was easily
the _worst_ setting.  

 These switches have nothing to do with the ImageWriter printing
uni- or bi-directionally; David Casseres explained that the IWII always
prints bidirectionally, except for the first few lines of the page, and
that this is under control of the printer's ROM.  He suggested I take
the printer to a dealer for alignment.  I may do that, since the print
quality is still not as good as the NLQ Pica sample packed with
the printer.  (I assume that the trip from the factory to the dealer
has something to do with this.)  But the new DIP switch setting is a 
major improvement.
