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 Internet Connections
A wired internet 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 wired cable, DSL, or fiber internet connection.
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. When using Wi-Fi, in the Windows Wi-Fi settings the network profile needs to be set to Private.
Cable/Fiber/Dial-up Connections
Cable and fiber connections are faster and more reliable than most other types of internet connections. Other types of connections are either slower or more subject to periodic loss of connectivity.
Due to the size of the TaxSlayer Pro program installation and some of the updates, a dial up connection is impractical. Anyone using a dial up connection should be prepared for very long download times and frequent dropped connections.
Satellite Internet Service
Satellite internet service is usually slower and more expensive than cable, DSL, or fiber, but it may be the only high speed option available in some rural areas, so it should mainly be considered when there is no other form of high speed internet service available.
