The Inventory Reports menu carries two entries for this report, Part Barcode Report and Product Barcode Report. Both open the same screen.
Only parts that actually have a barcode recorded against them appear here, so the list is usually much shorter than your full parts list. A part that has never been given a barcode will not show up, however you search for it — add the barcode to the part first, in Inventory, and it will then appear.
Each label carries three lines: your store name at the top, the part's identifier and name in the middle in the form #66 Air Filter, and the barcode image itself underneath. ARM allows a part to hold up to three barcodes, a primary and two alternatives, and each barcode gets a label of its own, so a part with more than one appears more than once on the sheet.
The labels are laid out three across, which is wider than a portrait page, so the third label in each row is cut off when you print in portrait. Set the print window to landscape before printing, or print a narrower selection by filtering to one category at a time. Because the labels print through your browser rather than as a PDF, the browser also adds its own date and page details around the edge of the sheet; those are your browser's, not ARM's, and can be turned off in the print window's own settings.
This report has no date range, no totals and no spreadsheet export. It describes the parts you hold now, and its only output is the printed sheet.
