Create Outlook calendar item with Python

I've created this script when I needed to keep track of my street workout performance. I was needed to have a reminder for each day that will tell me how much repetitions I should do today. So this script will create a bunch of Microsoft Outlook appointments in your calendar according to the "table" dictionary. The table is reduced for this example. It is easier to create such table in MS Excel, then convert it to text and paste into your favourite Python IDE. Please note that this code is using PyWin32 library. def addevent(start, subject):     import win32com.client     oOutlook = win32com.client.Dispatch("Outlook.Application")     appointment = oOutlook.CreateItem(1) # 1=outlook appointment item     appointment.Start = start     appointment.Subject = subject     appointment.Duration = 20     appointment.Location = 'Sprortground'     appointment.ReminderSet = True     appo...

Xerox 116-324 fault when printing .doc or .pdf containing callibri fonts

Image
Problem : You are unable to print .PDF or .DOCX documents which contain Calibri fonts. The Xerox 7345 or similar model sends 116-324 error code and needs to reboot. Resolution : Update you computer with the latest drivers from Xerox website. If you are on PCL driver - disable the Print Optimization feature in the driver. If you are on the PS driver set the PostScript Output Option to Optimize for Portability. The print file will be larger and printing will take more time. Another PS driver setting may screw up the text in your PowerPoint slides (as shown on the picture below). It is "PostScript Pass-through". If you have printouts like on the picture below, you better enable "PostScript Pass-through" (Printing preferences> Advanced> Driver section. )
