Sending files (printing) from the Perl PC is just adding them to the print queue and not actually sending the files. Tried restarting the PC, restarting Perl, plugging and unplugging the USB to Parallel cable,
The windows print manager shows the files as queued but with blank status. The printer status in the control panel for the laser shows ready. The Connect option in the print manager is greyed out, The settings (to check and reset the port id) require the admin PIN or password.
Tried all the above steps bother with and without the rotary (my project is rotary.)
Without admin permissions, this is the limit of what I know to do to fix printer communications errors on Windows. If anyone has admin access I’m happy to debug further if you help me.
