Common SPS-300 Programming Help

PLUs and Prices

PLUs can control item descriptions, prices, tax status, barcode lookup and reporting groups. A PLU that will not ring may be missing a price, barcode association or correct keyboard entry method.

Tax Programming

Tax settings affect taxable and non-taxable items, receipts and reports. Confirm the intended tax rules before making register changes.

Keyboard Programming

Programmable keys can provide access to items, departments, discounts, refunds, tenders and other checkout functions. Document the current layout before making major changes.

Receipt Messages

Supported configurations can store customer-facing business information such as the business name, address, phone number, website or return information.

Reports and Daily Closing

Review X and Z report behavior before changing closing routines or running reset reports.

SD Card Backup

Backup and restore procedures depend on the register configuration, software version, media and exact procedure. Follow the SPS-300 manual and confirm a backup before relying on it.

Before You Change SPS-300 Programming

  • Confirm the exact SPS-300 model.
  • Record the setting you need to change.
  • Preserve important PLUs, prices and tax information.
  • Print important reports when appropriate.
  • Back up programming when possible.
  • Change one setting at a time.
  • Test a normal sale, receipt and report afterward.
  • Do not clear memory unless you understand what will be erased.

SPS-300 Supplies and Peripherals

Receipt Paper

Confirm the exact printer and model before ordering paper. Paper width and printer configuration can differ by model.

Shop receipt paper

Barcode Scanners

Scanner compatibility depends on the model, port, cable, scanner interface, barcode type and matching PLU data. Do not assume a connector type proves compatibility.

Browse barcode scanners

Cash Drawers

Drawer issues can involve cable type, drawer assignment, lock position, tender programming or hardware.

Browse cash drawers

Receipt Printers

Printer troubleshooting can involve paper loading, printer settings, receipt/journal configuration or aging hardware. External-printer compatibility should be verified before purchase.

Common SPS-300 Problems

PLU Will Not Ring Up

Check the PLU record, price, barcode and keyboard assignment.

Tax Is Calculating Incorrectly

Review the programmed rate and item tax status before making broad changes.

Receipt Information Is Wrong

Check receipt text, date/time settings and printer configuration.

Barcode Scanner Will Not Work

Confirm interface, cable, register port, scanner programming, barcode symbology and corresponding PLU.

Cash Drawer Will Not Open

Check the lock, connection, assignment, no-sale/tender function and drawer hardware.

Backup Will Not Work

Review the SD card, formatting, register version and exact backup procedure. Do not depend on an unverified backup.

Review the troubleshooting guide, which covers symptom-by-symptom checks, error codes and what not to do before the cause is understood.

Repair the SPS-300 or Replace It?

Programming help may be enough when the register is reliable and the problem is limited to taxes, PLUs, receipt information, reports, keyboard setup or peripherals. Replacement may be better when printers or keys are failing, the register is unreliable or the business now needs touchscreen checkout or stronger inventory and reporting.

SPS-300 Frequently Asked Questions

What models are in the SPS-300 family?

Common models include SPS-320, SPS-340 and SPS-345. Confirm the full model because keyboard and printer arrangements differ.

Should I back up before changing programming?

Yes, whenever the model and configuration support a reliable backup. Also document important programming and print reports before major changes.

Can I connect a barcode scanner?

Some SPS-300 configurations support scanners, but the exact interface, cable, scanner setup and register programming must be verified.

When is replacement better than repair?

Replacement becomes more attractive when hardware is unreliable, parts are difficult to obtain or the business needs capabilities beyond the existing register.

Need SPS-300 Help?

One-time remote support and programming are available for supported equipment even if the register was purchased elsewhere.

Repair or replace?

Is it time to replace your SPS-300?

If the SPS-300 is unreliable or no longer fits the workflow, compare the current SPS-320, SPS-340 and SPS-345 direction while verifying keyboard style, printer setup and peripherals.

For this model

Which manual do you need?

Operating a register and reprogramming it are two different documents.

Find the complete model number on the identification label first, then look for the document that matches the job you are doing. Registers that look alike can use different procedures, so a manual for a neighbouring model is not a substitute. If only one document exists for your model, that is normal for some families.

Open the manual & documentation center →
Operator or user manual
Day-to-day selling: ringing items, tenders, voids, opening the drawer, changing paper, and running the reports a manager needs.
Programming or service manual
Setup and changes: taxes, departments, PLUs, prices, receipt messages, clerks, keyboard functions and system options.
Quick reference or setup sheet
A short guide for first installation and the most common daily tasks. Useful, but rarely enough for programming changes.
PC utility documentation
Only relevant if your model is supported by a PC tool and you have the matching cable or interface. Confirm the model before assuming a utility applies.

How paid help works

Straightforward remote support, billed by the block.

Remote support and programming are sold as time blocks, so you only pay for the work the register actually needs. We do not require a service contract, and we do not turn away a register because it was bought from another dealer, bought used, or came with the business.

  • $100 per hour for remote support and programming
  • $50 for a 30-minute block
  • Support hours are Monday to Friday, 9:00 AM to 5:00 PM Eastern - there is no 24/7 emergency line
  • No contract required; ongoing coverage is available separately
  • You do not need to have bought the register from us

What to send us

These are the same details the checkout asks for when you buy a support or programming block, so nothing is wasted.

  • Exact model from the label
  • Serial number if visible
  • Photo of the keyboard
  • What the register is doing now
  • The change or fix you need
  • Connected scanner / drawer / printer models
  • Recent changes to the register
