A number of users have used 3rd party vendors to print their codes, using other formats, with negative results. The problems do not become evident until after you the codes are in place.
The easiest way to mitigate against many of these issues is to print your codes on the recommended format which is 22mm, or 7/8 inch. If you must use another format, be sure to get a sample printed and put them into the production environment for a beta test. You can then iterate if issues surface.
Recommended QR Code Format
The mobile app supports the QR-code format generated and printed from CMMS. Codes are generated and exported to a PDF document in high resolution, print-ready format, with 30 QR codes per page. The PDF files can be printed on Avery address labels and attached to assets in your facility.
