1)Send the query HCOPy:DATA? via the GPIB.

2)Read the block response data via the GPIB.

3)Send the print/plot data part to the printer/plotter.

Figure 3.22 Hardcopy of screen on printer/plotter

PROGRAM EXAMPLE:

Select one of the supported GPIB plotters, set its address at 22 and connect the plotter via IEEE to the controller. Create a screen picture on the DSO that you want to plot and run the following program.

DIM addr(2)		’Dimensions address array.
DIM response AS	STRING * 15000	’Dimensions response string.
CALL IBTMO(0, 13)		’Timeout at 10 seconds.
CALL Send(0, 8,	"HCOPy:DEVice PM8277", 1)	’Selects the PM8277 plotter
CALL Send(0, 8,	"HCOPY:DATA?", 1)	’Requests for hardcopy data.
CALL Receive(0,	8, response$, 256)	’Reads the hardcopy data.
length = IBCNT%		’IBCNT = number of read bytes

PRINT "Number of hardcopy bytes ="; length ’*****

’The first 2 characters of the response block data are #0 (preamble for indefinite length). ’They must not be sent to the plotter; so, send characters 3 until 3+length-2.

’*****	’No End detection
CALL Send(0, 22, MID$(response$, 3, length - 2), 0)
CALL Send(0, 22, "", 1)	’End of data block
