I have been getting some conflicting information lately regarding the printing of payroll and corporate checks from my computer.On one hand, my companys IT guy states that I absolutely MUST use a Troy brand MICR toner cartridge. He says, and I quote, "if its not in a Troy box then you cant use it because Troy is the only brand certified for HP printers for check printing." He claims that, because of the economic crisis, banks are cracking down on such things and that our company can get fined for using a non-Troy toner, even though the toner we use is an MICR toner. He further states that banks are starting to crack down on using printers that are not officially certified for check-printing, and that in the near future well have to buy a new printer for the checks.On the other hand, my toner vendor sold my company a "Troy-compatible" MICR toner. Its made by a generic brand, but they guarantee their toner and state that it is an MICR toner and that its illegal for a bank to discriminate against their toner, citing the Robinson-Patman Act of 1936 (which doesnt quite seem to cover this issue, from what I read, as its about price discrimination relating to wholesalers selling to retailers).From my perspective, both parties are trying to sell me their own products, and it seems that both sides are either not completely truthful or are just misinformed.So I am turning to you, a neutral party, for information. Do I have to use a Troy toner cartridge with my HP LaserJet, and will I eventually need a new printer? Are we in jeopardy of being fined for printing our company checks with a generic-brand MICR and our HP printer?Does anyone have some valid information, and even better a website or other official written regulations/guidelines for check-printing?Thanks for your help, its appreciated! :).--Answer1:Are you printing on pre-printed check stock or are you actually printing on blank paper?If youre using pre-printed stock, do whatever you want. No one cares.If you are printing on blank paper and expect it to go through the bank properly, Id talk to someone at the bank. They might have better info.But under no circumstances does the government dictate whose products you are allowed to use.
