- For the longest time I have been using the CBM_MPS1000 printer driver
- to operate my 9 pin DMP-130 printer and have had acceptable results.
- There were a few differences between the printers though which would
- cause a couple of problems in doing graphics dumps (it would still
- work - but the line spacing between passes wasn't quite right...), so
- I decided to use PrtDrvGen to try and come up with a driver
- custom-made for the DMP-130.
-
- I managed to get everything to work okay up until I wanted to get
- higher graphics density output (low density graphic dumps work just
- fine...) I can get 1920 dots/line with my printer, but unfortunately
- it is only a 9 pin printer. There are no spaces between the dots
- horizontally, but to get rid of the vertical spaces, the CBM_MPS1000
- driver double- or triple-strikes the lines advancing the paper forward
- a tiny amount between passes. Since I don't know if this is a normal
- capability of printer drivers, forgive me if I am describing the
- obvious. If rows are numbered from the top starting with 'a', the
- driver would cause the printer (in highest density) to:
- - print rows a,d,g,j,m,p,s,v with the 8 pins in 1920 dots/line
- - advance the paper forward slightly
- - print rows b,e,h,k,n,q,t,w
- - advance the paper forward slightly
- - print rows c,f,i,l,o,r,u,x
- - advance the paper forward until the point where the next
- triple-striked band should begin.
-
- Anyway, sorry for being hard to understand, but the method worked
- great for systems such as TeX (I had no idea a 9-pin printer could
- look so good!) I am wondering if PrtDrvGen could be convinced to
- send a graphic dump in such an interlaced format somehow.
-
- Of course, if someone's already made a DMP-130 driver, that would be
- even better! :-)
-
- Please email responses as this group is too busy for me to keep a
- regular eye on.
-
- Thanks...Dan
