Can you print a picture in quiz?

[Walker, Chris]

You can use Quiz to send PCL or HPGL instructions to the printer.  The
easiest way to create the picture is to load your bitmap or whatever into a
program that will convert to PCL/HPGL.  I have used Corel Draw, but there
are probably others.

Getting Quiz to output the picture is more of an issue, because Quiz has
never heard of non-printing characters and automatically prints a newline
when it thinks you've printed enought to fill a line.  The cleanest solution
is to load the picture into a PCL macro before the Quiz report runs, so that
Quiz only needs to send the short "execute macro" instruction to print it.
Better still, you can specify to PCL that the macro be automatically
executed when a new page is initialized.  I use VMS, so I load the picture
as a page setup module (a predefined sequence that VMS extracts from a
library and sends to the printer).  No doubt there similar facilities on the
HP3000.

The sequence that prints the picture should end with an instruction to send
the printer's cursor to the position on the page where Quiz thinks it is.
The easiest solution is to print the picture first, then home the cursor.

I've asked on occasion for an enhancement to Quiz that would allow the print
width of a report item to be specified.  For example:

	;A long escape sequence that puts the cursor back where it started
	def escape-sequence char*80 width 0 = esc + "123456" .....

	;A 4-character heading that advances the cursor 8 positions
	def wide-heading char*12 width 8 = esc-double-width + "HEAD" +
esc-normal-width
