Thank you for reaching out to the Community. Yes, you can open your cash drawer using Gopayment and Epson TM m30 printer in QuickBooks. However, if you're unable to open and the printer won't print, these can be the following issue can occur:
The printer is unplugged or has no power
The printer status is paused
The print spooling process is damaged
The wrong printer driver has been installed
More than one instance of the printer has been installed
Additionally, I've added this article to learn more about connecting the cash drawer to your printer and it's troubleshooting steps: Cash drawer troubleshooting.
Please let me know if there's anything else I can do to help. Just add a comment below or mention my name. Have a great day, stay healthy!
Thanks Ailene. I neglected to mention that I am using Gopayment on my tablet. My bad. The tablet is running the latest version of the Android OS and Gopayment is up to date. I contacted the app developer and got referred here. The tablet, card reader, and printer are connected via Bluetooth and are working together. The printer prints, the card reader works and the transactions show up in my QBO account. I tested the drawer and cable using my PayPal app and Star Micronics printer and it opened fine. I can find no option to enable a cash drawer in the Gopayment Android app. What did I miss? We have a couple of weeks to figure this out before I'll start using this configuration. I really do not want to have to go back to PayPal.
The cash drawer should work perfectly fine using an android app. Once your Bluetooth is turned on, you can enable the receipt printer and cash drawer inside the GoPayment app.
Go to the App Settings.
Locate, then tap Printer and Cash Drawer.
Turn it on, then try to test print.
Also, please make sure to have the compatible or recommended printers as well as the cable used to connect the printer for better results. For your guide, check out the details from this link: What devices are compatible with QuickBooks Point of Sale?.
