Sort of, it's the amount of memory the printer driver troubles to
access---when last I looked at HP inkjet drivers, they had to accept
Windows GDI calls from the printer subsystem of Windows, then convert
that into PCL(probably 3 here)---said conversion includes making PCL
bitmap fonts of all the fonts used, then the converted PCL commands
(which are native to the printer) are sent down to it. Not sure if the
driver is running out of memory making the fonts and sending incomplete
ones, or if the printer is running out of memory in storing
them---likely the former 'cause the latter usually causes an error
message on the printer.

TeX documents unfortunately use more fonts than is typical, so stress
this conversion.

Only if it has a better written printer driver, or is able to sidestep
the problem 'cause it uses the native (PostScript / PDF) datastream, or
rasterizes all the characters as bitmaps (I believe Epson printers do

Is the output off your desktop printer the final result or just for

GhostScript is a good (and free) alternative here.
