Cut after last label only

[stuartlynne]

My application prints either one or two labels on pre-cut 62x100 labels.

I need to cut after the last label only.

If a single label is printed cut after it.

If two labels are printed cut only after the second.

I am using pdf2image convert_from_bytes to generate an images list (from pdf on stdin.)

And then:

model = 'QL-710W'
printer = 'tcp://192.168.40.16:9100'
kwargs = { 'rotate': '90', 'cut': False, 'label': labelsize,
qlr = BrotherQLRaster(model)
instructions = convert(qlr, images, **kwargs)
send(instructions=instructions, printer_identifier=printer, backend_identifier=backend, blocking=True)

Setting cut to False I get no cut. Setting it to True I get a cut after each label.

Suggestions? Thanks!

This does not seem to be supported without further changes as both command sets handled here are supported by your model:

brother_ql/brother_ql/conversion.py

Lines 175 to 187 in 56cf439

	try:
	if cut:
	qlr.add_autocut(True)
	qlr.add_cut_every(1)
	except BrotherQLUnsupportedCmd:
	pass
	try:
	qlr.dpi_600 = dpi_600
	qlr.cut_at_end = cut
	qlr.two_color_printing = True if red else False
	qlr.add_expanded_mode()
	except BrotherQLUnsupportedCmd:
	pass

You might try to use

convert(qlr, images, **kwargs)
qlr.cut_at_end = True
qlr.add_expanded_mode()
instructions = qlr.data

but I have not tested it and this probably will not actually work.

No, that did not work.

Then you might want to create your custom raster class:

class CutAtEndRaster(BrotherQLRaster):
    def add_expanded_mode(self):
        self.cut_at_end = True
        return super().add_expanded_mode()


qlr = CutAtEndRaster(model)
instructions = convert(qlr, images, **kwargs)
send(instructions=instructions, printer_identifier=printer, backend_identifier=backend, blocking=True)

[stuartlynne]

That gets a cut after each label.

Did you set cut=False for this? Then you are only left with doing the same as in my previous comment with add_cut_every(n) and setting n to the number of pages you have while enabling cut=True as far as I understand.

[stuartlynne]

This is cuts every label if 'cut' is True, or no cuts if False ┆ kwargs = { 'rotate': '90', 'cut': True, 'label': labelsize, } ┆ qlr = BrotherQLRaster(model) ┆ convert(qlr, images, **kwargs) ┆ qlr.add_cut_every(2) ┆ instructions = qlr.data ┆ send(instructions=instructions, printer_identifier=printer, backend_identifier=backend, blocking=True) This was the previous. Again with 'cut' False no cuts, 'cut' True cuts after each label. ┆ kwargs = { 'rotate': '90', 'cut': False, 'label': labelsize, } ┆ class CutAtEndRaster(BrotherQLRaster): ┆ def add_expanded_mode(self): ┆ self.cut_at_end = True ┆ super().add_expanded_mode() ┆ qlr = CutAtEndRaster(model) ┆ convert(qlr, images, **kwargs) ┆ qlr.add_expanded_mode() ┆ instructions = qlr.data ┆ send(instructions=instructions, printer_identifier=printer, backend_identifier=backend, blocking=True)

convert(qlr, images, **kwargs)
qlr.add_cut_every(2)

is wrong. You need a custom BrotherQLRaster class which overrides add_cut_every with your custom logic and cut=True set, as convert does not allow you to pass these parameters directly.

[stuartlynne]

I thought something like this would work, but still get cuts after every label: ┆ kwargs = { 'rotate': '90', 'cut': False, 'label': labelsize, } ┆ class CutAtEndRaster(BrotherQLRaster): ┆ def __init__(self, model, pages): ┆ self.pages = pages ┆ self.page_count = 0 ┆ print('pages: %s' % (pages), file=sys.stderr) ┆ super(CutAtEndRaster, self).__init__(model) ┆ ┆ def add_autocut(self, flag): ┆ self.page_count += 1 ┆ print('add_autocut: flag: %s page_count: %s' % (flag, self.page_count), file=sys.stderr) ┆ if self.page_count == self.pages: ┆ print('add_autocut: calling super', file=sys.stderr) ┆ super(CutAtEndRaster, self).add_autocut(flag) ┆ ┆ def add_cut_every(self, n): ┆ print('add_cut_every: n: %s overide: %s' % (n, self.pages), file=sys.stderr) ┆ if self.page_count == self.pages: ┆ print('add_autocut: calling super', file=sys.stderr) ┆ super(CutAtEndRaster, self).add_cut_every(self.pages) ┆ ┆ qlr = CutAtEndRaster(model, len(images)) ┆ convert(qlr, images, **kwargs) ┆ instructions = qlr.data ┆ send(instructions=instructions, printer_identifier=printer, backend_identifier=backend, blocking=True)
