Below are recommendations related to check printing, including check stock and envelopes.


Purchase/Designate a Printer for Check Printing

Purchase a new or dedicate an existing printer for printing checks. Inn-Flow does not recommend using HP Officejet printers as these printers require customized configuration to print checks properly. Inn-Flow does recommend using any other inkjet or laser printer. Inn-Flow recommends following standard banking practices and using magnetic ink cartridges. These can be purchased from any office supply store or online. Note: Non-purchase of magnetic ink will not inhibit check printing/cashing. This is only a recommendation. 


Purchase Check Stock and Envelopes

Check Requirements: 

  • Blank, 3-part check stock
  • Heights of each check section are: top = 4”, middle = 3.5”, bottom = 3.5”
  • Check must be on the bottom section of the check stock
  • You may not use pre-printed checks with Inn-Flow
  • Perforations: 4" and 7 1/2" from the top
  • All check information will be printed by your Inn-Flow site onto blank check stock

Print a sample check for each bank account. While Inn-Flow gives you the capability to print checks from any computer and printer, it’s highly recommended that you dedicate which printers and computers will be used to print checks. Printer and computer print settings, if not configured properly, can distort the image of the check when printed. Use the Print Sample Check button, located within Accounting > Register > HID > Account > 3-dot menu, Edit Account feature, to test a printer and a computer and confirm settings are accurate. Print a sample check from each of the bank accounts. The page size should be set to “auto” or “letter”. The scaling should be set to “none” or “100%”.  Confirm that all check details printed and are located in the proper position. Most importantly, confirm that the routing and bank numbers appear on the bottom of the check.
