Networking
If you are preparing tax returns on more than one computer in an office, we recommend having a local network technician ensure that all computers are on the same network before contacting TaxSlayer Pro for technical support. They should ensure the network is configured for TaxSlayer Pro to function properly.
Printer Recommendations
TaxSlayer Pro is compatible with any Windows compatible printer. When considering a printer for your office, purchase a printer with the highest printing speed (pages per minute) that your budget can afford.
If you will be printing checks for bank products, we recommend using a laser printer rather than an ink jet printer.
Scanners used with the PaperCut program should be fully TWAIN compliant. Unfortunately, due to scanner manufacturer design variations, the only way to truly tell if a scanner is compatible with PaperCut is to test it using PaperCut.
Scanner Recommendations
While most scanners are TWAIN or WIA compliant and should work with TaxSlayer Pro without issue, over the years we have discovered several scanners that are incompatible with TaxSlayer Pro:
- Neat - Neat is TWAIN compliant but only intended to function with Neat software.
- Ricoh ScanSnap - The ScanSnap series uses a proprietary driver and document management software.
- Lexmark - Depending on the scanner model, not all TWAIN and WIA features are supported.
Wireless Network Connection
A wired network connection is recommended over a wireless (Wi-Fi) connection. Wi-Fi is more susceptible to service outages and speed fluctuations. These outages can cause problems when trying to transmit returns, receive acknowledgments, and/or get updates. For these reasons TaxSlayer Pro recommends a more reliable ethernet connection. When using Wi-Fi, in the Windows Wi-Fi settings the network profile should be set to Private.
Additionally, care must be taken to avoid public Wi-Fi. Your PC's security can be compromised, and to avoid this some functions of TaxSlayer Pro are inhibited on public Wi-Fi.
Internet Service Provider Connection
Internet service providers in your area may offer service via cable, fiber, satellite, or public hotspot. For security reasons, avoid using a public hotspot. Beyond that, evaluate your options in terms of their speed, cost, convenience, and reliability.
