The Print Commands - HP 39gs Master Manual

These commands were supplied for use with the battery operated HP infra-red thermal printer that is designed
for use with any of the 39g family. This printer was originally designed for the first calculator in this family,
the hp 38g, released in 1995. Very few of them sold because it was far easier to simply use the connectivity
software to capture screens and images and then just paste them into a document on the PC. At the time of
writing I was unable to find any reference to it on the HP website and it may no longer be available.
Because it uses the infra-red port the commands will not operate with the hp 40gs. There may be a brief
display of the communications symbol, a small arrow, in the top right corner of the display but there will be no
other result.
