Gemini Industries Printer user manual

Fundamenta/sof Dot Matrix Printing

Note: If we used ‘I” or CHR$(76) instead of “K:’we would be asking Gemini for high-resolution graphics. If we used “y”or CHR$(121),we would be asking for high-resolution graphics with double speed, and if we used “2”or CHR$(122),we would be asking for ultra-high-resolution graphics at normal speed.

nl and n2 represent the set of ASCII codes that define how many columns of graphics to print on a line. If you want to print “x” number of columns of graphics on a line, then:

nl is the remainder of x/256, and n2 is the quotient of x/256

Note: For those of you who are computer-wise and curious:

nl = x

MODULO 256, and n2 = INTEGER of xl256

What does all this mean to the rest of us? The following table might help.

If the number
of columns,x,		then,		then
ranges from:		nl	Is	n2 is
1 to	255			0
256to	511	x-x256		1
512 to	767	x-	512	2
768 to 1023		x-	768	3
1024 to 1279		X-	1024	4
1280 to 1535		x -	1280	5
1536 to 1791		x -	1536	6
1792 to 1920		x-1792		7

Remember: Gemini-70X can only print up to 480 columns in low-resolution mode, 960 columns in high-resolution mode, and 1920 columns in ultra-high-resolution mode. The Gemini-15Xcan print 816 columns in low resolution, 1632 in high-resolution, and 3264 in ultra-high-resolution.
