[comp.sys.atari.st] Prtblk help in MWC

mdf@trwrb.UUCP (09/30/87)

I need some help with the Prtblk XBIOS function in the MWC package.  I'm
using version 1.1 (I haven't received my upgrade yet), and have entered
the Prtblk example in the manual.  I have also entered the Prtblk.h header
file and included it in the main program.  
From the developer's docs, I discovered that prior to any Prtblk calls, 
the system variable _prtcnt (0x04ee) must be set to 1.  I did that.  
My printer is a Gemini 10X, capable of the 120 horizontal X 144 vertical
resolution described in the developer's prtblk docs.
Everything compiles and runs fine, but my question deals with the quality
of printer output.  I understand for the 1/120 bitmap mode, only the
'draft' and not the 'final' mapping is available.  Is this the reason
that a regular screen dump via
the Alt/Help key combination produces a denser dot pattern than the 
output of prtblk?


Any help would be greatly appreciated.  Thanks in advance
