This page contains a list of hardware that is known to be compatible with the Grindless POS system. There are more devices that are compatible with our POS system than what is listed below, but these specific devices have been tested to be compatible with our system.
Links to buy products are provided where possible. You are also welcome to shop around for the best prices on any hardware listed (double-check the model numbers when doing so). It is strongly recommended to coordinate with a Grindless On-boarding Specialist on our team before making purchases to ensure that your purchases are accurate and essential. If you already have hardware present on-site and you would like us to look into whether or not it is compatible with our POS, please let your representative know during the sign-up process.
In order to use hardware (like cash drawers/printers/scanners), the Grindless POS must be installed and used from a Windows-based computer. Grindless LLC does not sell or supply computers directly, so you may use existing computers at your store(s) or purchase computers from a local or online supplier.
- Storage: 250MB for application, >10GB spare disk space
- Solid-state disks suggested, but not required
- CPU: Intel G4600 3.6ghz 2 core, 4 threads or higher. Or Intel i3 equivalent or higher.
- Memory: 4GB minimum, 8GB recommended
- Operating System: Windows 10 (64-bit)
- Display: HD resolution recommended for best experience (1080p or higher)
- Internet: 10mbps or higher
- The Grindless POS is a web-based application and makes frequent requests over the internet to our server. If your internet connection is slow or unstable, your experience using the application may be degraded.
The Grindless POS application is not very demanding on computers. In general, if the computer can perform common “office” related tasks like checking emails and browsing the web, then it will likely be suitable to use with the Grindless POS.

Important: “Enable bidrectional support” should be unchecked in the printer’s port settings in Windows (restart the PC + printer after changing).
Product: AGP VB320-BL1616 Standard-Duty Cash Drawer, Vasario Series
Cash Drawer Cable: APG CD-101A Printer Cable
A sturdy metal cash drawer that opens automatically when the POS pops the drawer out after a sale. The cash drawer connects through the receipt printer. You will very likely need to purchase a special cable (linked above) in order to connect your cash drawer to your printer.
Many barcode scanners will work with our POS by default, however, additional functionality is enabled if you have a scanner that supports both 2D barcodes and a feature called “SNAPI“. We recommend using Zebra-brand scanners for the best experience.

After installing the device drivers (and rebooting your PC), your scanner will need to be configured in order to have certain features enabled. There are two methods to configure your scanner(s):
- Configuration barcodes. Click here to view these barcodes from your web browser and begin scanning them.
- Zebra’s 123Scan Utility for Windows.
Note: if using a wireless scanner and connecting with bluetooth (instead of the USB charging cradle/receiver), you will need to enable bluetooth pairing mode on your scanner and then connect to the device from Windows’ device settings menu. Instructions are available in the device’s manual. We can also help you with this step.
Print product price tags, including barcodes, on adhesive stickers. Also print custom stickers for labeling things around your store and re-use sticker designs across your stores.
Product: DYMO LabelWriter 450 Turbo Direct Thermal Label Printer
Optional: Inexpensive 3rd party labels (2 ¼” x 1 ¼”): HL-30334 6 Rolls; 1,000 Labels per Roll; DYMO-Compatible
Driver Download: Dymo Label v8.7.3 (Windows 10 64-bit)
Note: If you use Dymo’s newer app, “Dymo Connect”, then you will NOT be able to create your own custom label templates and use them with the Point of Sale. Either app allows you to print labels from the POS, but only the older “Dymo Label” app allows you to create custom templates.
IMPORTANT – We strongly recommend avoiding Dymo LabelWriter 550 models. These newer models have sensors in them which can detect if the labels you’re using were not made by Dymo. This means you cannot buy cheaper 3rd-party labels and will have to instead buy label rolls that are made by Dymo and are made for the 550 model specifically. Even genuine Dymo labels that are designed for the older 450 model will not work on this newer model. For this reason, we recommend purchasing the older “LabelWriter 450” models (standard, Turbo, or XL), which do not have this limitation.
A small screen that is visible to the customer during checkout which provides information, such as the total balance due for the current order being transacted.
Supported device: HP LD220 USB. Driver page for device: Click Here. Download the Driver and OPOS software packages. After installation, the settings panel in the Grindless POS application should use “opos:HP POS Pole Display” for the “Line Display LDN” option.
More devices may be compatible (contact us for details).
The Grindless POS can be run from Apple iPad devices instead of traditional Windows-based computers. We have an app available for iOS which can be downloaded to each iPad you will be using at each iPad-equipped POS station. Your iPad tablet(s) must be running iOS version 13 or higher. Older iPads may not be capable of running iOS version 13.

You can use many of the hardware devices listed above in the “Recommended Hardware” section with iPads, so long as you use the printer listed below.
- Receipt Printer
The only supported Customer Display device is the Star Micronics SCD222U. The HP brand Customer Display above is not compatible with iPads.
iPads are particularly sensitive about which devices they will work with, so we recommend consulting with a Grindless team member prior to purchasing any equipment.
Desktop vs. Mobile Access
The Grindless POS can be accessed from virtually any modern web browser, such as Google Chrome,
The Grindless POS is a web-based system, meaning you can access it from virtually any device that can browse websites. This includes desktops, laptops, tablets, and most modern smartphones. If possible, we recommend using the system from a Windows-based PC for the best possible user experience. The POS is usable from mobile devices, however, certain features may be limited and are only possible through a desktop computer from within our Desktop POS app.
