Powershell Out-Printer breaks Format-Table column

Iam trying to use Format-Table to print some process data. I started with testing the output directly in the shell. Something along the lines of (Get-Process is just a substitute for my data):

Get-Process | Format-Table ProcessName, Id

The problem is that the first column has some larger cells and i needed to set up some formatting like this:

$tableFormat = @{Expression={$_.ProcessName}; width=70}, @{Expression={$_.Handles}};
Get-Process | Format-Table $tableFormat

In both cases, the output looked fine inside the shell. This is an example with $tableFormat:

When i attempt to print the table to the default printer like this

...
Get-Process | Format-Table $tableFormat | lp

The result has broken columns (taken from a pdf printer, real output looks the same):

Other things I've tried so far:

Set the column alignment for all columns explicitly to left
autoSize(makes things worse)

This problem might be related to my previous question, when i still tried to manually format the table with tabs. See: Why does Powershell Out-Printer ignore `f (new page) in text?

At first glance, this looks like a font problem. It may or may not be, but it's at least worth checking this out. In some fonts, all characters are the same width. In others, each character may have a unique width.

The console interface to powershell typically uses a fixed width font. The formatting you get from format-table may assume that all characters are the same width. If you print it on a printer with a variable width font, you'll get output like what you have shown us.

You may be able to check this out by somehow specifying to your printer that a fixed width font is to be used. "Courier" is one such font. I can't tell you how to do that in your case, because I don't know the particulars.

If my guess is on target, then specifying a fixed width font should make the columns look aligned again.

Another thing to check out is where the tab stops are set.
