Printing large images as multiple A4 sheets using IrfanView

Poster Printer works with your existing printer to allow you to print documents at a much larger size than would fit on a single printed page

(open source, Windows)

You need to set the orientation and print settings in each sheet separately. Manually, you'd use the options on the Page Layout ribbon for that.

Sheet1 can be portrait with print area set from A1 to G30, for example. Sheet2 can be landscape with print area set from A1 to Q26, for example and scaled to print on one page.

Select each sheet individually and see the correct print preview.

Select both Sheet1 and Sheet2, or use "Print Entire Workbook" and the print preview will show Sheet1 in portrait and Sheet2 in landscape.

Here are some screenshots of the print preview, page 1 and page 2.
