Relationship between OpenType fonts and PostScript printers, and impact on printing performance?
Printer-installed fonts tend not to be used at all, as PostScript output from MacOS (and PDFs) use unique names to reference the Font data that they contain, e.g. "Helvetica-Bold+AAXYZ". 
There is no benefit to having a printer that stores font data, because the font names in the printer won't match the unique names in the PS output. Also, the amount of data saved is in the order of Kb, and negligible in terms of file size and performance.
The PostScript output from MacOS encodes the glyph data from PostScript, OpenType and TrueType fonts in a variety of ways within the data stream. It is not rastered beforehand.
I suspect that most laser printers these days contain ample memory, compared to those in 'pre-OS X days'. Some printers, particularly larger, 'network' devices, have memory expansion slots where you can add DIMMs. 


In short: you do not have to worry about any lack of quality or performance by using OTF or TT fonts, compared to Type1 PS fonts.
