I am having a similar issue. Switched to QBO in Dec 2019. Purchased new check printer and new style checks at that time. After performing the initial set-up of my checks successfully, have printed without issue for 6 months.  Have made no changes to printer, or program, but suddently checks started printing too low on page (amount block is printing on signature line). Have completed all trouble shooting tips and verified all settings. Have tried printing from browser, from Adobe, have updated Adobe program, have disconnected and reconnected printer, logged in and out, and have tried any other QBO and Adobe magic tricks I could find ... but nothing is working. I now have to print all checks to blank paper ( so that they record in QBO) and hand write my actual checks ( not a susatinable work around). Please help!
