I have been using standard, full sheet checks, three on a page with tear-off strip on the bottom for a long time. I only print checks occasionally, so usually it is only one check at a time that needs to be printed. During the last year or so, The following has happened to me perhaps two times. The full page has always printed the top check with no problem. The next time I need to print a check, when it asks "how many checks on the page", I will answer "two". Then, I go ahead and tell it to print, without realizing that it DIDN'T ask me, "Is the tear-off strip attached"? So, of course, since I inserted the remaining two checks rotated sideways, it prints in portrait form, which, of course, comes out as sideways printing, and I have two ruined checks.
I went through this twice until I finally realized that my printer setup for partial page had changed from "Center" to "Portrait". I believe this happened last year also. I'm hitting myself in the head because I should have realized I had a setup problem since it didn't ask me, "Do you have a tear-off strip"?
Any ideas as to why this printer setting should have changed?
