We have a WPF application which can perform either a report preview or a report print.
Both requests use the same code.
- Call the report service which gets the report from Microsoft Report Services.
- Convert the report into the desired format (in this case PDF).
- Then return the report as a byte array.
The result is then written to a temporary file as a binary stream, and either popped into a window to preview or start a Process to print.
In both cases the temporary file is passed.
Print Preview works flawlessly! But Print Report will print with all occurances of ‘ti’ disappearing. I see there is a printer escape sequence of ESC t NUL/SOH and I assume that if, for some reason, an escape character gets into that stream that ti will result in an ignored print sequence. Thus the missing characters.
My first question is if anyone has ever experienced this with generated PDF reports?
My second question (obviously) is if anyone knows of a utility I can use to view the binary data in the file being printed, to see what is in the file just before every ‘ti’ sequence?
After a great deal of searching I came across a post on the Adobe forum that states that version 8 had a bug where it was not printing character combinations. Once I dug deeper it seems that it has returned and the suggested workaround fixed our issue.
Workaround: Do a print as image.
Adobe seems to be unable to do the most basic of what their software must do, print the exact content!
