Strange print behavior with HP50 and HP82240B

[cahlucas]

Hi all,
While programming an application, I noticed that there are HP50g calculators that do not print the full 24 characters per line on the infrared printer, using the PR1 command. For my application it is nice if the full 24 characters per line are used. If I run the self-test on the printer, there is no problem, i.e. 24 characters are printed per line. Resetting the printer has also done nothing, the problem is with the calculator. Are there any settings in the calculator that I have overlooked? How can I get the full 24 characters on the printer, regardless of the calculator used? I hope to hear from someone soon. Thanks in advance! Sincerely, Karel.
